  • Product overview

    PhosphoTracer assays use a traditional immuno-sandwich format, but with a major difference both the analyte and the assay reagents are added to the PhosphoTracer assay microplate at the same time. After a short incubation period, unbound assay reagents and analytes are washed away, and immuno-complexes containing both antibodies are detected. The process can take as little as 60 minutes to complete.

    PhosphoTracer kits also allow a higher degree of assay flexibility. In contrast to other ELISA formats, no antibodies are present on the assay microplate itself, so assays for several different targets can be performed in different wells on the same microplate. Simply mix the lysate with your target reagents of choice, using the microplate configuration of your choice.

    A whole new way of performing cellular assays, PhosphoTracer takes the hard work out of running a standard ELISA, while still giving the high quality results expected from a sandwich immunoassay. Fully self-contained kits are supplied in convenient 96-well packs. Simple to use and highly sensitive PhosphoTracer kits are designed to get results, fast.

     

    Abcam’s PhosphoTracer phospho-STAT5 assay kits detect endogenous levels of STAT5A and STAT5B (GenBank Accessions NP_003143 and NP_036580) in cellular lysates. Total STAT5 assay kits detect STAT5 irrespective of phosphorylation.



    The substrate used with the HRP conjugated detection antibody is a combination of 10-Acetyl-3,7-dihydroxyphenoxazine (ADHP) (wavelength exc/em = 530-540nm / 590-600nm, a highly sensitive and stable substrate for HRP) and ADHP Dilution Buffer (a stabilized H2O2 solution). Learn more about the fluorogenic substrate, ADHP.

Properties

  • FunctionCarries out a dual function: signal transduction and activation of transcription. Binds to the GAS element and activates PRL-induced transcription.
  • Sequence similaritiesBelongs to the transcription factor STAT family.
    Contains 1 SH2 domain.
  • Post-translational
    modifications    Tyrosine phosphorylated in response to IL-2, IL-3, IL-7, IL-15, GM-CSF, growth hormone, prolactin, erythropoietin and thrombopoietin. Tyrosine phosphorylation is required for DNA-binding activity and dimerization. Serine phosphorylation is also required for maximal transcriptional activity.
  • Cellular localizationCytoplasm. Nucleus. Translocated into the nucleus in response to phosphorylation.

      Day 1: A431 cells were seeded at 25K/well in a 96 well tissue culture plate in medium containing 10% FBS. Day 2: The cells were stimulated with various concentrations of EGF for 15 minutes. The media was removed, and the cells were lysed with 125 µL/well freshly prepared Lysis Mix, with shaking for 10 min. Lysates (50 µL) were transferred to a PhosphoTracer assay plate and analyzed for either phospho STAT5 using the standard PhosphoTracer protocol. Briefly, Antibody Mix specific for phospho-STAT5 (50 µL/well), was added to the lysate, and the plate was incubated for 1 hr at room temp, with shaking. The plate was washed and Substrate Mix was added to the wells. The plate was covered in foil and incubated for 10 min with shaking. Signal in the wells was determined using a plate reader.

    Can you recommend 2 antibody pairs please.

    One pair against mouse phospho stat5

    and the other pair against mouse total stat5 for ELISA/MSD etc.

    Thank you for contacting us.
    While we have not validated our individual primary antibodies as sELISA pairs, we do have three PhosphoTracer ELISA kits that may interest you:
