Sophy (Verified Customer) (02-27-2023)

The antibody was used at 1:1000 for western blot. The signal showed up but not as strong as expected. But since this was the only antibody purchased for Rab5A, I had no comparison to antibodies to other vendors.

  • Applications: Western Blot
  • Cell Tissue Type: NSCLC cells

Xin (Verified Customer) (01-24-2022)

Very good antibody in WB (25 kD) with a high titer

  • Applications: Western Blot
  • Primary Antibody Dilution: 1:4000
  • Cell Tissue Type: mouse brain lysate
