Validation Data Gallery

• 

  WB analysis using 83837-1-RR (same clone as 83837-1-PBS)

  Various lysates were subjected to SDS PAGE followed by western blot with 83837-1-RR (Beta Arrestin 1 antibody) at dilution of 1:4000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 83837-1-PBS in a different storage buffer formulation.

• 

  WB analysis using 83837-1-RR (same clone as 83837-1-PBS)

  Various lysates were subjected to SDS PAGE followed by western blot with 83837-1-RR (Arrestin antibody) at dilution of 1:1000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 83837-1-PBS in a different storage buffer formulation.

• 

  WB analysis using 83837-1-RR (same clone as 83837-1-PBS)

  HEK-293 cells were subjected to SDS PAGE followed by western blot with 83837-1-RR (Arrestin antibody) at dilution of 1:1000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 83837-1-PBS in a different storage buffer formulation.

Background Information

β-Arrestins (ARRBs), the best known regulators of G protein-coupled receptor signaling, are versatile and multifunctional adapter proteins that regulate diverse cellular functions, including cell growth, apoptosis and immune responses. Overexpression of beta Arrestin 1 has been found in various cancers, indicating it as a potential therapeutic target for cancer treatment. Recently expression of ARRB1 in saliva has been identified as a candidate circadian biomarker. ARRB1 migrated as a doublet of two bands of 45 and 55 kDa (PMID:28947386).
