The CRBN65 antibody detects recombinant and endogenous CRBN protein with high sensitivity. (A) Recombinant human full-length CRBN (0·2–60 ng) along with DF15 and DF15R cell extracts (20 μg/lane) were separated by sodium dodecyl sulfate polyacrylamide gel electrophoresis and probed with CRBN65 antibody (1:1000). (B) Linear regression analysis using CRBN signal as measured on LI-COR Oddysey for rhCRBN is linear in the 0·2–60 ng range, and CRBN protein measured in DF15 cells falls within linear range of detection. CRBN, cereblon; kDa, kiloDalton; Mol W, molecular weight; R2, coefficient of determination.
