Untreated and tunicamycin treated HeLa cells were subjected to SDS PAGE followed by western blot with 81462-1-RR (CHOP; GADD153 antibody) at dilution of 1:5000 incubated at room temperature for 1.5 hours.

Untreated and tunicamycin treated Jurkat cells were subjected to SDS PAGE followed by western blot with 81462-1-RR (CHOP; GADD153 antibody) at dilution of 1:5000 incubated at room temperature for 1.5 hours.

Chromatin was prepared from NIH/3T3 cells treated with Tunicamycin (2ug/ml, overnigh). Cells were fixed with formaldehyde for 10 minutes. The ChIP was performed with 20 µg of cross-linked chromatin, 5 µg of CHOP (81462-1-RR) or 5 ug of Normal Rabbit IgG (98136-1-RR), and 20 µl of Protein A Magarose Beads. The immunoprecipitated DNA was quantified by real-time PCR.

Biolayer interferometry (BLl) kinetic assays of 81462-1-RR against Human CHOP/GADD153 were performed. The affinity constant is 104 nM.
