Antibody information

Rabbit monoclonal IgG

Company: Cell Signaling

Antibody: Drosha

Catalog number: 3364

Summary: Rabbit monoclonal IgG against a synthetic peptide corresponding to residues surrounding Gly953 of human Drosha. Reacts with human and mouse. Suitable for western blot and immunoprecipitation.

Validation Method

Western blot

Sample

WT and Drosha-KO murine embryonic stem cells (mESCs). Total cellular protein was extracted from 1 × 106 mESC pellets using a NP-40–based lysis buffer (1% NP-40, 137 mM NaCl, 20 mM Tris-HCl, and 1 mM EDTA) complemented with EDTA-free protease inhibitor cocktail (Roche).

Secondary incubation

rabbit IgG HRP-linked antibody 1:20,000 diluted (08/2012; Cell Signaling Technology)

Detection

Clarify Western ECL substrate (Bio-Rad Laboratories) kit and detected using an imaging system (ChemiDoc MP; Bio-Rad Laboratories).
