Anti-Rac1 Western blot Comparison


Question 1:  How do I know whether the Cdc42 monoclonal antibody is good for Western blotting and IF?

Answer 1: The datasheet (Cat. # ACD03) and the website's individual product page (ACD03) descibe the applications for all Cytoskeleton's antibodies. The Cdc42 antibody (Cat. # ACD03) was raised against a peptide sequence of human Cdc42 (amino acids 123-141).  The Cdc42 antibody will not cross-react with a ten-fold excess of RhoA, RhoB, RhoC, Rac1, Rac2, or Rac3 proteins. Non-specific bands have been observed at higher molecular weight in about 50% of cell lines tested.  The antibody has been tested by western blotting and immunocytochemistry.  Please see the Citations tab for references that have used this antibody. 


Question 2:  Can I test a sample of the RhoA monoclonal antibody?

Answer 2:  All of Cytoskeleton’s antibodies are rigorously quality-controlled and tested under the conditions described in the product datasheet.  In the rare event of a problem with an antibody, please contact our technical service group ( for assistance.  Free samples of the RhoA antibody (cat# ARH03) are not available.  However, please contact Cytoskeleton’s customer service department (303-322-2254 or to check on any special discount offers.
