Recombinant Human Macrophage Inflammatory Protein-3 Beta (CCL19)
|Description||CCL19 is a chemokine that belongs to the CC family of growth factors and signals through the CCR7 receptor. CCl19 has been shown to be expressed in the thymus, lymph nodes and in activated bone marrow stromal cells. When anti-inflammatory signals are released, expression of CCL19 gets down-regulated – specifically by IL-10.|
|Molecular Weight||9.1 kDa|
|Endotoxin Level||<1.0 EU/μg of recombinant protein as determined by the LAL method.|
|Purity||>95% as determined by SDS-PAGE|
|Bioactivity||Measured by its ability to chemoattract 5 10 day cultured human peripheral blood lymphocytes (PBL). The ED(50) for this effect is typically 0.10.3 µg/mL.|
|Formulation||Lyophilized from a 0.2 μm filtered solution in Acetonitrile and TFA with BSA as a carrier protein|
|Reconstitution||Reconstitute at 25 μg/mL in sterile PBS containing at least 0.1% human or bovine serum albumin|
|Storage||The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.|
|Usage||For research use only. Not for diagnostic or therapeutic use.|
· Endotoxin is generally measured in Endotoxin Units per milliliter (EU/mL).
· For recombinant proteins: EU is reported per microgram of protein.
· One EU = 0.1-0.2 ng endotoxin/µg of protein.
· At abm, we do the LAL chromogenic assays that can detect down to 0.01 EU/ml.
