    • Anti-Bovine Serum Albumin is shown to detect BSA in bovine serum diluted 1:100 (lane 1) and in purified BSA preparations at 0.5 mg/ml (lane 2). In both lanes 20 ul of sample was applied. Primary antibody is diluted 1:5000 in PBS and is reacted for 1.5 h at room temperature.

      Detection occurs using a 1:5000 dilution of IRDye800TM Conjugated Goat-a-Mouse IgG reacted for 1 h at room temperature. Visualization is by near-infrared (IR) western blotting analysis using the Odyssey® Infrared Imaging System developed by LI-COR. Other detection systems will yield similar results.

    Ab9092 was purified from ascites.

    Thank you for your enquiry. We would like to confirm that this antibody derived from ascites.

    Albumin is the most abundant protein in serum. I don't know what dilutions you did to human serum? The antibody would non-specifically bind to HSA when HSA overwhelmingly presented in the loading sample. I suggest you try to dilute both sera at least 1...

    Thank you for your message. We would suggest trying PBS with 0.1% Tween 20 and 1.5% fish gel as blocking and dilution buffer. Load 20uL of purified BSA at 0.5mg/mL and use 1:1000 dilution of the primary antibody.

    For the protocol please reference our ELISA under Methods on the web. The BSA we've been using is Fraction V (IgG and Protease free).
