bs-70359R

DATASHEET

Host: Rabbit

Target Protein: Blasticidin S Deaminase

Specificity: The antibody detects a 13 kDa* protein corresponding to the molecular mass of Bsd on SDS-PAGE immunoblots of 293 cells transfected with a lentiviral vector that expresses the Bsd gene product, but is not detected in mock transfected cells.

Clonality: Polyclonal

Isotype: IgG

Swiss Prot: P0C2P0

Source: A synthetic peptide (coupled to KLH) corresponding to amino acid residues in the N-terminal region of Blasticidin S Deaminase* from Aspergillus Terreus.

Purification: Antigen Affinity purification

Storage Buffer: PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol

Storage: Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.

Background:

Retroviral vectors are commonly used for gene expression in vitro and in vivo. The structure of these vectors usually consists of one gene of interest and a selectable marker gene. Fast selection without damaging cells is a critical step for significant gene expression. Blasticidin S deaminase (Bsd) isolated from Bacillus cereus has a neutralizing action on the highly toxic antibiotic blasticidin. A variety of commercially available retroviral vectors, such lentiviral expression systems, utilize Bsd expression for selection using blasticidin. This selectable marker allows selection of stable mammalian cell lines in as little as one week. bs-70359R is a Bsd antibody that can detect Bsd expression in cells transfected with blasticidin-selectable constructs. This antibody is useful for detection of successful gene transfer in constructs that utilize blasticidin selection.
