| Name | Human Cutaneous Angiosarcoma Cell Line (KU-CAS3) |
| Description |
The KU-CAS3 cell line is a novel human cutaneous angiosarcoma model derived from scalp primary angiosarcoma tissue. KU-CAS3 shows endothelial cell properties, with cobblestone appearance at confluence. These cells are CD31 positive, display tube forming activity, actively uptake LDL, express vWF, show high levels of adrenergic β2 receptor, VEGF1 and VEGF2 receptors. STR profiliing was used for cell line authentication. These cells have tumorigenic potential in vivo and are suitable for cutaneous angiosarcoma research.

PriCoat™ T25 Flasks (G299) coated with Gelatin Coating Solution (0.1%) (TM063) are required for optimal cell adhesion and growth. The base medium for this cell line is Prigrow X Series Medium (TM8028) + 1% Penicillin/Streptomycin Solution (G255), 37.0°C, 5% CO₂. Note: Morphology will change with contact inhibition; subculture cells when 60-70% confluent. |
| Unpacking and Storage Instructions |
1. Visually examine the packaging containers for signs of leakage or breakage. 2. Immediately transfer frozen cells from dry ice packaging to a temperature below -130°C, preferably in liquid nitrogen vapor phase storage, until ready for use. To ensure the highest level of viability, thaw the vial and initiate culture as soon as possible upon receipt. If continued storage is desired, the vial should only be stored below -130°C or in liquid nitrogen vapor phase. Do not store at -70°C, as it will result in loss of viability. |
| Thawing Protocol |
1. Thaw cells quickly in a 37°C water bath while agitating gently (maximum 2 minutes). The vial cap should be kept above the water level to minimize the risk of contamination. 2. Decontaminate the vial by spraying and wiping the exterior of the vial with 70% ethanol. From this point onwards, all operations should be strictly carried out inside a biological safety cabinet using aseptic conditions. 3. Transfer the cell suspension into a 15ml sterile conical tube containing 5ml of pre-warmed, complete growth media, supplemented with additional FBS (10%). Centrifuge cells at 125xg for 5-7 minutes. 4. Aspirate the supernatant without disturbing the cell pellet. Re-suspend the cell pellet in the recommended pre-warmed, complete growth media and dispense into a T25 culture flask. 5. Incubate the cells at the recommended conditions. |
| Subculture Protocol |
Cells are sensitive to trypsin; Gentle Dissociation Solution (TM080) is recommended for subculture procedures. Volumes given below are for a T75 flask; proportionally increase or decrease the volume as required per culture vessel size. Subculture cells once the culture vessel is 80% confluent. 1. Aspirate the culture media, and add 2-3ml of pre-warmed Gentle Dissociation Solution (TM080) to the culture vessel. 2. Observe the cells under a microscope to confirm detachment (typically within 2-10 minutes). Cells that are difficult to detach can be put in 37°C, for several minutes to facilitate detachment. 3. Neutralize the Gentle Dissociation Solution (TM080) by adding an equal volume of the complete growth media supplemented with 10% FBS into the culture vessel. 4. Transfer the culture suspension into a sterile centrifuge tube, and centrifuge at 125xg for 5 minutes. The actual centrifuge duration and speed may vary depending on the cell type. 5. Aspirate the supernatant, and re-suspend the pellet with pre-warmed fresh complete growth media. Add appropriate aliquots of the cell suspension to new culture vessels, as desired. 6. Incubate the cells at the recommended conditions. 7. Do not allow culture vessel to become >90% confluent; contact inhibition will result in morphological changes. |

How should I handle live cells once I receive them? |
|
|
Please refer to our Cell Handling and Thawing Guidelines for detailed instructions on receiving, thawing, and culturing live cells: |
| I want to make sure these cells express my gene of interest before I decide to buy the cell line. Can you provide a sample so this can be tested? | |
|
We do not perform extensive downstream characterization, or gene expression profiling of our cell lines. However, you can check the ‘References’ tab to see if a publication is available, or you can contact us to see if RNA or cell lysates are available for your cell line of interest. Please directly contact us for further information at quotes@abmgood.com.
|
| Does abm's PriGrow series medium contain antibiotics? | |
|
No, the medium does not contain antibiotics and needs to be supplemented by the end-user as desired.
|
| Do I need to use abm's media and Applied Cell Extracellular Matrix (G422) to culture my cells? | |
|
We strongly encourage using the recommended media and culture conditions described in the "Growth Conditions" section as they have been optimized for cell growth. Other supplier's media and coating conditions have not been tested.
|
| What is the difference between Applied Cell Extracellular Matrix (G422) and Collagen Coating? | |
|
The main component of our Applied Cell Extracellular Matrix (G422) is type I collagen specifically. For more information on abm's Applied Cell Extracellular Matrix please visit: http://www.abmgood.com/Applied-Cell-Extracellular-Matrix-G422.html.
|
| Do I have to use T25 ECM-coated flasks for growing the cells? | |
|
We strongly recommend thawing cells in the T25 flasks specified on the cell-specific product page to ensure optimal post-thaw recovery of the frozen cells before testing other culture vessels.
|
| If I want to plate these cells to multi-well plates (e.g. 96 well plates) or dishes, how should I prepare the plates? | |
| What percentage of Trypsin-EDTA should be used to subculture cells? Can I use Trypsin-EDTA containing phenol red? | |
|
The standard concentration used for subculturing is 0.25% Trypsin-EDTA, available at abm (Cat. No. TM050). Yes, Trypsin-EDTA containing phenol red can be used as it does not interfere with trypsinization.
|
| How often do I need to change the media? | |
|
Media should be changed every 2-3 days or as specified within the recommended growth conditions.
|
| Why are these cells classified as biosafety level II? | |
|
We follow the CDC-NIH recommendations that all mammalian sourced products should be handled at the Biological Safety Level 2 to minimize exposure of potentially infectious products. This information can be found in 'Biosafety in Microbiological and Biomedical Laboratories' (1999). Your institution's Safety Officer or Technical Services will be able to make the call as to whether BioSafety Level I is possible with these cells at your site, if desired.
|
| How long can I store frozen vials? | |
|
Cells that are properly frozen using an effective cryoprotective agent can be stored in liquid nitrogen vapor phase (or below -130°C) indefinitely without affecting viability.
|
| What is the recommended storage temperature for cells? | |
|
In general, if you received:
|
| Can I substitute heat-inactivated FBS with FBS or vice versa? | |
|
FBS and heat-inactivated FBS are different in their composition; they cannot be substituted for one another.
|
| My cells are not detaching, what method do you recommend to trypsinize the cells? | |
|
| How are live cells shipped? | |
|
Live cells are shipped as a live culture in a T12.5 flask. Cells are seeded at an optimal confluency to avoid metabolic waste build up during transport. In addition, we thoroughly test our cell lines for functional freeze-thaw recovery. For more information on how to handle live cells, please view our detailed instructions here (https://www.abmgood.com/uploads/document/Cell_Handling_Instructions_Upon_Arrival_150623.pdf).
|
| Why are cells not attaching and forming clumps after subculturing with trypsin? | |
|
Cells form clumps and display attachment issues when the trypsinization agent is not effectively neutralized. To completely neutralize the trypsin agent, add an equal amount of complete growth media prior to centrifugation. Subtle changes in culture conditions, particularly in pH and the quality of serum used in the growth medium, may also affect the amount of clumping exhibited by the cells.
|
| Why are my cells forming clumps after plating? | |
|
It is important to ensure cell clumps are broken up through gentle re-suspension by pipetting up and down several times after pelleting cells by centrifugation. This will ensure a homogenous single cell suspension for even plating.
|
| Do I need to add the selection drug to the complete growth medium? | |
|
We recommend maintaining selection pressure using the drug concentration specified in the Growth Conditions section.
|
| Where can I find the CoA for my product? | |
|
Certificates of analysis can be found here (https://www.abmgood.com/CoA-Library.html).
|
|
What is your warranty or return policy? |
|

|
How many times can cells divide? |
|
|
The number of times cells can divide depends on the cell type:
|
|
What is the difference between spontaneous immortalization and tumor-derived cells? |
|
|
Spontaneously immortalized cells arise when normal cells acquire the ability to proliferate indefinitely in culture without intentional genetic manipulation. These cells are not derived from tumors but may undergo genetic or phenotypic changes during immortalization.
Tumor-derived cells are established directly from cancerous tissue and typically retain characteristics associated with malignancy, such as altered growth control and genetic instability. |
|
Do I need Applied Cell Extracellular Matrix (G422) if I am using PriCoat™ flasks? |
|
|
Please refer to the Growth Conditions section of your specific product page. This section will indicate whether Applied Cell Extracellular Matrix (G422), PriCoat™ flasks, or both are recommended for optimal cell attachment and growth, as requirements may vary by cell type. |
