What did the customer think?Antibody Specificity:

Antibody RPPA Rating:

Testing results were provided independently by J. Huang at Newcastle University. They stated “HeLa cell lysates were used. Western blot signals were detected using an Odyssey (Li-Cor) machine). Four positive protein bands were detected around the size of assumed Bim protein from 17 to 25KDas using anti-Bim (STJ91855) antibody at 1:500 dilution and a rabbit Alexa fluor 680 secondary antibody (in red).”

What Was The Protocol?Treatment of Materials When cells were cultured to 70%-80% plating density, lysis buffer with protease inhibitors

(Sigma) and equal volume of 2X loading buffer were added and heated at 100˚C for 10 minutes. Supernatant was collected after centrifugation at 12,000 rpm for 25 minutes at 4°C and used for 10% Bis-Tris plus gel for protein separation.

Gel Electrophoresis 10% polyacrylamide gel, constant voltage 160 V, 60 minutes.

Transfer 0.45 µm PVDF membrane, 1 piece of gel (wet transfer), constant current 80 Amp for 90 minutes.

Blocking 1X Odyssey blocking solution for 2 hours at RT

Primary Antibody Probing Primary antibody was added to the 1X Odyssey blocking solution with 1:500 dilution, and the membrane was incubated at 4˚C overnight with agitation.

Membrane Wash 1X TBST wash 3 times

Secondary Antibody Probing Secondary antibody was added to 1X Odyssey blocking solution with 1:1000 dilution ratio, for 1.5 hours at RT

Membrane Wash 1X TBST wash 3 times

Visualization Fluorescent signals were visualized using a Li-Cor Odyseey machine using 700nm and 800nm detecting channels
