Antibody was affinity purified using an epitope specific to Sirt1 immobilized on solid support. The epitope recognized by A300-688A maps to a region between residue 700 and the C-terminus (residue 747) of human Silent Mating Type Information Regulation 2 homolog 1 using the numbering given in entry NP_036370.2 (GeneID 23411). Immunoglobulin concentration was determined by extinction coefficient: absorbance at 280 nm of 1.4 equals 1.0 mg of IgG.

Detection of human Sirt1 by western blot

Detection of human Sirt1 by western blot and immunoprecipitation. expndtw-6 Samples: Whole cell lysate from HeLa (5, 15 and 50 µg for WB; 1 mg for IP, 20% of IP loaded) and HEK293T (T; 50 µg) cells. Antibodies: Affinity purified rabbit anti-Sirt1 antibody BL3203 (Cat. No. A300-688A) used for WB at 0.04 µg/ml (A) and 1 µg/ml (B) and used for IP at 3 µg/mg lysate. Sirt1 was also immunoprecipitated using rabbit anti-Sirt1 antibodies BL3200 (Cat. No. A300-687A) and BL3201. Detection: Chemiluminescence with exposure times of 3 seconds (A) and 30 seconds (B).
