AAV Blank Control Vector (EF1a) (SV40-Luc)
|Unit quantity||1 µg|
|Shipping Conditions||AAV are stable at room temperature for short term storage and are shipped with gel ice packs. Do not store at -20°C or 4°C for long term. For long term storage, it is recommended to store the viruses at -80°C and avoid repeated freeze-thaw cycles. Before storing at -80°C, it is advisable to make small aliquots to avoid repeated freeze-thaw cycles.|
|Storage Condition||AAV viruses are shipped with dry ice. For long term storage, it is recommended to store the viruses at -80°C in small aliquots to avoid repeated freeze-thaw cycles.|
|Disclaimer||1) Disclaimer for Transcript Variants: The provided accession number refers to the transcript (mRNA) sequence for this product. The molecular sequence of this clone aligns with the gene accession number as a point of reference only. However, individual transcript sequences of the same gene can differ through naturally occurring variations (e.g. polymorphisms), each with its own valid existence. This clone is substantially in agreement with the reference, but a complete review of all prevailing variants is recommended prior to use. All sales are final.|
2) Disclaimer for Gene Sequence: The provided accession number refers to the transcript (mRNA) sequence for this product. Please verify that this is the desired transcript sequence by cross-referencing. This is important because a single gene can have multiple different transcripts owing to naturally occurring variations. All sales are final.
3) Disclaimer for Intended Use: All of abm's vectors and viral particles are for research use ONLY and NOT for therapeutic/diagnostic applications. abm is not liable for any repercussions arising from the use of its vector(s) in therapeutic/diagnostic application(s).
4) Disclaimer for Extra Nucleotides: Cloning may lead to the insertion of extra nucleotides at the 5' or 3' end of the target sequence which, in most cases, is innocuous to the stability/functionality of the construct.
5) abm guarantees that at least 1 out of the 3 sgRNA constructs purchased in a set designed to be used with Cas9 Nuclease will result in gene knock-out due to frameshift mutations in over 50% of cells, after successful infection and drug selection. This guarantee applies to sgRNAs designed to target human, mouse or rat genes only. If knock-out is not achieved in extremely rare cases, a one-time replacement of another set of 3 targets with alternative sgRNA sequences will be provided. To qualify for this replacement, customers must examine knock-out efficiency by Surveyor assay. Before sending your inquiry, please make sure you have optimized your experiments as far as possible. This includes (where applicable) increasing and optimizing your MOI, increasing the duration of infection (up to 72 h), and carrying out clone screening before assaying for knock-out. Please also provide data to show that a reporter virus was used to optimize the MOI for your target cell line. Customers must provide adequate data to show >80% infection efficiency with a positive control, plus additional qPCR data to evaluate the level of mRNA expression.
For vector transfection, please evaluate the vector transfection efficiency by detecting Cas9 or puromycin expression for the 'All-in-One' vectors using qPCR, or neomycin for constructs containing only the sgRNA. In addition, please provide Surveyor Assay or Sanger Sequencing data on at least 20 isolated clones.
abm limits its obligation and liability for the success of this technology to providing one replacement of any sgRNA lentivector product only. The replacement set will not be covered by the same guarantee. If these constructs are also considered to be ineffective then the gene is most likely not susceptible to sgRNA knock-out.
|Are your pPB protein expression vectors high or low copy number plasmids?|
Our protein expression vectors are medium copy number plasmids and can be amplified using any standard miniprep or midi/maxi prep kits. There is no standard protocol that fits all proteins, therefore recombinant protein expression will need to be optimized and determined experimentally.
|When the protein is expressed from this vector, which enzyme do I need to use to remove my tag?|
The enzyme required to remove the tag (if possible) will depend upon the vector backbone corresponding to your product: 1) pPB-C-His: the His tag is NOT cleavable. 2) pPB-His-GST: the His-GST tag can be cleaved using TEV protease. 3) pPB-His-MBP: the His-MBP tag can be cleaved using TEV protease. 4) pPB-N-His: the His tag can be cleaved with Thrombin. 5) pPM-C-HA: the HA tag is NOT cleavable. 6) pPM-C-His: the His tag is NOT cleavable. 7) pPM-N-D-C-HA: the N-terminal D-tag can be cleaved using TEV protease. The C-terminal HA tag is NOT cleavable. 8) pPM-N-D-C-His: the N-terminal D-tag can be cleaved using TEV protease. The C-terminal His tag is NOT cleavable.
