General description

Neomycin phosphotransferase II confers resistance to kanamycin and neomycin in bacteria and G418 (Geneticin®, G418 Sulfate) in mammalian cells. These antibiotics bind to ribosomal components and inhibit protein synthesis. NPT II inhibits these antibiotics through phosphorylation, which is thought to interfere with their active transport into the cell. Immunoblot analysis of transfected cell lysates with anti NPT II can be used to gauge relative transfection efficiencies in experiments where multiple transfections are performed in parallel with different plasmids.

Specificity

Recognizes NPT II, Mr ~30 kDa

Immunogen

Full length neomycin phosphotransferase (NPT) II

Application

Anti-Neomycin Phosphotransferase II Antibody is an antibody against Neomycin Phosphotransferase II for use in WB.

Western Blot Analysis:
1-2 μg/mL dilutions of a previous lot detected NPT II in RIPA lysates from Cos-1 cells transfected with pUSE, harboring the neomycin resistance gene.

Quality

Routinely evaluated by Western Blot on transiently transfected Cos-1 cells.

Western Blot Analysis:
1-2 μg/mL of a previous lot detected NPT II in RIPA lysate from Cos-1 cells transfected with pUSE, harboring the neomycin resistance gene.

Target description

~30 kDa

Physical form

Format: Purified
Protein A purified
Purified rabbit polyclonal IgG in buffer containing 0.1 M Tris-glycine, pH 7.4, 0.15 M NaCl, 0.05% sodium azide before the addition of glycerol to 30%. Liquid at -20°C.

Storage and Stability

Stable for 1 year at 2 - 8°C from date of receipt.

Handling Recommendations:
Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at 2 - 8°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance. Note: Variability in freezer temperatures below 2 - 8°C may cause glycerol containing solutions to become frozen during storage.

Analysis Note

Control
RIPA lysates from Cos-1 cells transfected with pUSE, harboring the neomycin resistance gene
