Antibody Sampler Kit

Application / Dilution

Species Reactivity

Hu, Rt, Ms, Rb




The IκBα phospho-regulation antibody sampler kit can be used to detect IκBα phosphorylation on Ser-32/Ser-36, Tyr-42, and Tyr-305. The kit also includes a polyclonal antibody to monitor total IκBα expression levels and secondary reagents for detection of these antibodies.

Western blot analysis of Jurkat cells untreated (lanes 1 & 3) or treated with TNFα (1 nM). The blots were probed with anti-IκBα (lanes 1 & 2) or anti-IκBα (Ser-32/Ser-36) (lanes 3 & 4).

Western blot analysis of A431 cells treated with pervanadate (1 mM) for 30 min. Blots were probed with anti-IκBα (lane 1), anti-IκBα (Tyr-42) (IP1031; lanes 2-5), or anti-IκBα (Tyr-305) (IP1041; lanes 6-9). In some lanes, the antibodies were used in the absence (lane 2 & 6) or presence of IκBα (Tyr-42) (lane 3 & 8) or IκBα (Tyr-305) (lane 4 & 7) blocking peptides, or BSA conjugated to phospho-tyrosine (lane 5 & 9).

Mouse monoclonal and rabbit polyclonal antibodies are supplied in phosphate-buffered saline, 50% glycerol, 1 mg/ml BSA, and 0.05% sodium azide. The secondary reagents are supplied in the same buffer without azide. Store all at –20°C. Stable for 1 year.

The products are are safely shipped at ambient temperature for both domestic and international shipments. Each product is guaranteed to match the specifications as indicated on the corresponding technical data sheet. Please store at -20C upon arrival for long term storage.

*All molecular weights (MW) are confirmed by comparison to Bio-Rad Rainbow Markers and to western blot mobilities of known proteins with similar MW.
