  • 描述

    兔单克隆抗体[E132] to JAK1 (phospho Y1034 + Y1035) + JAK2 (phospho Y1007 + Y1008)
  • 宿主

    Rabbit
  • 特异性

    This antibody is phospho-specific and only detects phosphorylated JAK2 on Tyrosine 1007 and 1008 (pY1007+Y1008) and JAK1 on Tyrosine 1034 and 1035 (pY1034+Y1035). According to our ELISA results, this antibody preferentially recognizes phospho Y1007. Stimulation may be required to allow detection of the phosphorylated protein. Please see images below for recommended treatment conditions and positive controls.

    The mouse and rat recommendation is based on the WB results. We do not guarantee IHC-P for mouse and rat.

Question

I purchased 12 antibodies from your company.
Some didn't work and I need your help.

I used mouse liver tissue. I attached our lab's protocol.
Apply 25ug of protein in each well.
The gel I used is NuPAGE 4-12% Bis-Tris Gel.
I tried 1:1000 dilution of JAK2 and 1:5000 of phospho JAK2 in 5%NFDM TBST.
Both didn't work. No bands, even with 2 hour exposure.

Please give me your advice.

Answer

Thank you for bringing this to our attention. I am sorry to read that two of the antibodies you purchased are not staining blots of your mouse liver samples.

I am assuming the transfer from gel to blot was effective, if your protocol worked with other blots of these samples.

I recommend stripping a blot and re-blocking with 1% BSA without detergent for one hour, and also diluting the antibodies in this 1% BSA solution, instead of non-fat dry milk. I also recommend trying the antibodies at higher concentrations, for instance 1/250 for anti-JAK2 ab39636, and 1/2000 for the phospho-Jak2 antibody, ab32101.

Please let me know the results. If this modification fails, I will be happy to provide replacements, or a credit or refund. The phosphorylation in the liver may be difficult to detect if it is not induced. If possible, I recommend including a positive control such as the treated mouse liver sample shown on the datasheet of ab68268.

Asked on Mar 13 2012

Answer

Thank you for your enquiry.

I can confirm that this antibody has been tested on the following and these would be suitable positive controls:

Rat uterine cell line Treated with 1µg/mL Prolactin for 1 hour.

Jurkat cell lysate treated with GM-CSF (Granulocyte-macrophage colony-stimulating factor) or Pervanadate

I am sorry we do not provide lysates of these cell lines that have beenpre treated. Unfortunately, we did not test any cell lines that do not require pretreatment. I was not able to find positive controls for phosphorylated Jak2 in the literature, and from what I find stimulation is required for expression of this phosphorylated state of the protein in cell culture.

I can suggest to do a further literature search for more information.

I am sorry we have not suitable positive controls to provide from our catalog on this occasion, however I hope this information is useful to you. If you have any further questions, please do not hesitate to contact me.

Question

I have a question regarding the treatment of tissue prior to applying the primary antibody. Do you recommend microwave? Enzymatic? The tissue I have in mind is human salivary gland. I'm planning to use ab6672, ab59389, ab39636, ab32101, ab31370 and ab30646. Different recommendations?

Answer

Thank you for contacting us. The treatment of PFA-fixed, paraffin embedded sections (IHC-P) before incubation with priamry antibody would include antigen retrieval, blocking of endogenous peroxidases (if HRP is being used for detection), and blocking of non-specific proteins. Here are the protocol details for the respective antibodies: ab30646, ab31370, ab39636, ab59389: 1. antigen retrieval: 10 mM citrate buffer (pH6.0) boil in pressure cooker 2. block with 3% H2O2 (in fresh methanol) for 15 minutes at room temperature 3. block with 3% BSA in TBS for 30 minutes ab6672: antigen retrieval: citrate buffer pH 6 and proteinase K digestion have been tried successfully as well as no antigen retrieval. 2. block with 3% hydrogen peroxide for 10 min 3. block with 1-10% Serum for up to 1 hour ab32101: 1. antigen retrieval:10 mM Sodium Citrate Buffer, pH 6.0 in rice cooker 2. block with 3% hydrogen peroxide for 10 min 3. block with PBS + 10% serum I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Question

Dear Sirs, I am potentially very interested in purchasing this mAb but I would like first to know: 1) whether this mAb is specific for the Y1007-Y1008 phosphorylated form of JAK2 or also detects the non-phosphorylated form (could you please provide a western blot, as the one shown in the website is not informative in this regard?) 2) whether you had the chance to test this mAb also on formalin-fixed paraffin-embedded decalcified bone marrow biopsies; in fact, the additional decalcification step required by bone material often denatures epitopes otherwise resistant to formalin fixation and paraffin embedding 3) which tissues can be used as positive controls, besides lung adenocarcinoma 4) what is the frequency of positivity of lung adenocarcinoma ?

Asked on Oct 16 2006

Answer

Thank you for contacting us. In answer to your questions: 1. The antibody ab32101 is specific to the phosphorylated protein. We do not have another Western blot but we are confident, given the dot blot result, that this antibody will not recognize unphosphorylated JAK2. 2. We have not tested the antibody on bone marrow but our Abpromise guarantee covers this application. 3. Any carcinoma should serve well as a positive control: colon, breast, renal. 4. We do not know how often lung adenocarcinoma tissue reacts positively with this antibody. I hope this information helps. Please do not hesitate to contact us if you need any more advice or information.
