Background

CRBN/Cereblon, a substrate receptor for the CRL4 E3 ubiquitin ligase, was originally identified for its role in autosomal recessive nonsyndromic mental retardation (1). CRBN’s role in the regulation of the AMPK pathway has been linked to various human diseases, including cardiovascular disease and obesity, and its involvement in proteasomal degradation may be important in neuropsychiatric diseases (2). CRBN has also been shown to enhance the effects of immunomodulatory drugs (IMiDs) in multiple myeloma, and may be a predictive marker for therapy (2-4).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.

CRBN (F4I7F) Rabbit mAb

Western Blotting Image 1: CRBN (F4I7F) Rabbit mAb Expand Image
Western blot analysis of extracts from various cell lines using CRBN (F4I7F) Rabbit mAb (upper) or GAPDH (D16H11) XP® Rabbit mAb #5174 (lower). Low expression of CRBN protein in NCI-H23 and SK-MEL-28 cells is consistent with the predicted expression pattern.
Immunoprecipitation Image 1: CRBN (F4I7F) Rabbit mAb Expand Image
Immunoprecipitation of CRBN protein from PC-3 cell extracts. Lane 1 is 10% input, lane 2 is Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is CRBN (F4I7F) Rabbit mAb. Western blot analysis was performed using CRBN (F4I7F) Rabbit mAb. Mouse Anti-Rabbit IgG (Light-Chain Specific) (D4W3E) mAb (HRP Conjugate) #93702 was used as a secondary antibody.
