This technical support questionnaire summarizes a Western blot experiment testing the BCAR 3 antibody. Mouse corneal tissue cultured in different media was used as the test sample. The sample was prepared using lysis buffer and each lane contained 80 μg of protein. The primary antibody, BCAR 3, was tested at a 1/500 dilution overnight at 4°C. A single band near 93 kDa was observed, consistent with the expected molecular weight. Actin was used as a control.
