What did the customer think?Antibody Specificity:

Antibody RPPA Rating:

Testing results were provided independently by J. Huang at Newcastle University. They stated “Assumed Phospho-Bim protein band was detected at the position of 22KD (in red) as suggested from provided data sheet by anti-phospho-Bim (S59, STJ91225) antibody with 1:500 dilution) and a rabbit Alexa fluor 680 secondary antibody. The antibody also detected a protein band at around 32KD (in red with asterisk), which has not been mentioned from the provided data sheet. An actin band is also illustrated in green at 46KD using the actin antibody from Abcam (ab6276) and the mouse Dylight 800 conjugated secondary antibody.”

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
