Target

  • Function

    Tyrosine kinase of the non-receptor type, involved in the IFN-alpha/beta/gamma signal pathway. Kinase partner for the interleukin (IL)-2 receptor.

  • Tissue specificity

    Expressed at higher levels in primary colon tumors than in normal colon tissue. The expression level in metastatic colon tumors is comparable to the expression level in normal colon tissue.

  • Sequence similarities

    Belongs to the protein kinase superfamily. Tyr protein kinase family. JAK subfamily.
    Contains 1 FERM domain.
    Contains 1 protein kinase domain.
    Contains 1 SH2 domain.

  • Domain

    Possesses two phosphotransferase domains. The second one probably contains the catalytic domain (By similarity), while the presence of slight differences suggest a different role for domain 1.
    The FERM domain mediates interaction with JAKMIP1.

  • Cellular localization

    Endomembrane system. Wholly intracellular, possibly membrane associated.

The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab47435, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h.

    Question

    Dear Sir/Madam,   I purchased your antibody ab-47435 and despite following your protocols and recommended antibody concentrations it has failed to work on both western blot and immunofluorescence, two applications you claim this antibody works for. For this reason I would like to kindly request either a refund of the money paid or a substitute product (antibody) that will work to detect human Jak1 in western blot and immunofluorescence.   With best wishes,

    Answer

    Please accept my apologies for you having trouble with ab47435. The anti-JAK1 antibody is covered under our Abpromise, which states that we guarantee all of our antibodies for 6 months to work as stated on the datasheet. In the case of ab47435, it is guaranteed to work in ICC and WB on human samples. If the antibody fails to work as guaranteed if we cannot help resolve these issues, then will gladly replace the antibody or process a refund. I would be very happy to help you try and troubleshoot some of the issues you are having. To do this could you please provide me some information on the protocols that you have tried? For the western blot, are you seeing no bands when you develop your blot? Or are you seeing multiple bands, or high background? If you are seeing nothing, what primary antibody concentrations have you tried and what is the total protein concentration that you are loading on your gel? Also do you have a positive control on your gel? I ask as may be either increasing the antibody concentration or the protein concentration loaded onto the gel may help resolve seeing no bands. Incubating the antibody O/N at 4C would also be beneficial. If you are having issues with high background on your membrane, then if you are using milk as your blocking reagent, switching to BSA may help and vice-versa. For the ICC, what tissue/cell samples are you using? Again depending on whether you are seeing no signal or high background, either increasing the antibody concentration or increasing the blocking (or changing the blocking reagent) could prove helpful. As I mentioned previously, this antibody is covered under our Abpromise and so if we cannot resolve these issues I would be happy to send you another JAK1 antibody or a refund. I look forward to your repl
