  • General notes

    This antibody was developed as part of a collaboration between Abcam and the lab of Dr. Kevan Shokat at University of California at San Francisco.

    It is possible to use ab92570 with ab138911 as a kinase reaction reagent for the identification of direct kinase substrates as mentioned in Allen JJ et al. Nat Methods 4:511-6 (2007).

    After the kinase of interest has accepted ATP-γ-S (ab138911), p-Nitrobenzyl mesylate (ab138910) can be used to alkylate the thiophospholyation site on the substrates. ab92570 is introduced to identify the tagged substrates.

  • Primary antibody notes
    ab92570 can be used to detect kinase substrates containing thiophosphate esters following the kinase reaction as described by J. Allen and colleagues in Nature methods 2007. This antibody as allow researchers to follow this approach to study kinase-substrate relationships of interest. The antibody is also context independent in that it can recognize serine, threonine, and tyrosine thiophosphorylated residues in a multitude of kinase phosphorylation consensus motifs.
    In order for this antibody to work in WB and IP, the customer needs to perform a specific kinase reaction using ATP gamma S and PNBM.
    See specific Protocol at the bottom of this page for details.

    Lane 1 : JNK1 protein (10ng) incubated with c-jun-GST substrate (1ug)
    Lane 2 : JNK1 protein (10ng) incubated with c-jun-GST substrate (1ug) using alkylation with PNBM (2.5mM).
    Lane 3 : JNK1 protein (10ng) incubated with c-jun-GST substrate (1ug) using ATP-gamma-S
    Lane 4 : JNK1 protein (10ng) incubated with c-jun-GST substrate (1ug) using ATP-gamma-S followed by alkylation with PNBM (2.5mM).

    In vitro kinase reaction was carried out for 30 minutes at room temperature. PNBM alkylation (2.5mM) was for 2 hours at room temperature. Reaction products were analyzed by western blot with thiophosphate ester specific ab92570 at 1/5000, alpha-GST antibody confirms equal loading.

The rabbit monoclonal antibodies (RabMAbs) can use the same anti-rabbit IgG secondary antibody that you would use with a rabbit polyclonal antibody. For Western blot, we have a line of secondary antibodies called AbExcel, which have been thoroughly tested in WB and can be used at 1:2000-1:20000 dilutions. For anti-rabbit, I'd suggest ab16284:

The main difference between ab92570 and ab133473 is the composition of the storage buffer.
The ab133473 is ideal for IP because it is supplied as cell culture supernatant with 0.01% sodium azide and the IgG concentration is at least 1 mg/ml, which is higher than ab92570.
Ab92570 can be used for IP, but it will require more antibody per reaction. This is why we launched the IP version (ab133473), which has higher concentration and no BSA in the buffer.
