  • 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 p38 MAPKalpha assay kits detect endogenous levels of p38 MAPKalpha (GenBank Accession NP_001306) in cellular lysates. The phospho-p38 MAPKalpha assay detects p38 MAPKalpha only when phosphorylated at Thr180/Tyr182. The total p38 MAPKalpha assay detects p38 MAPKalpha irrespective of phosphorylation status.

    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.

  • FunctionResponds to activation by environmental stress, pro-inflammatory cytokines and lipopolysaccharide (LPS) by phosphorylating a number of transcription factors, such as ELK1 and ATF2 and several downstream kinases, such as MAPKAPK2 and MAPKAPK5. Plays a critical role in the production of some cytokines, for example IL-6. May play a role in stabilization of EPO mRNA during hypoxic stress. Isoform Mxi2 activation is stimulated by mitogens and oxidative stress and only poorly phosphorylates ELK1 and ATF2. Isoform Exip may play a role in the early onset of apoptosis.
  • Tissue specificityBrain, heart, placenta, pancreas and skeletal muscle. Expressed to a lesser extent in lung, liver and kidney.
  • Sequence similaritiesBelongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.
    Contains 1 protein kinase domain.
  • DomainThe TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
  • Post-translational
    Dually phosphorylated on Thr-180 and Tyr-182, which activates the enzyme.
    Phosphorylated upon DNA damage, probably by ATM or ATR.

  • As shown, using the p38 MAPKalpha assay kits, a significant stimulation of p38 MAPKalpha phosphorylation at Thr180/Tyr182 is detected in HEK293 cells treated with anisomycin for 30 minutes compared with untreated cells, while no change in total p38 MAPKalpha levels is observed.
  • Using the PhosphoTracer phospho-p38 MAPKalpha assay, the length of assay incubation time that was required to detect recombinant phospho-p38 MAPKalpha was examined. After 15 mins, phospho-p38 MAPKalpha concentrations of approximately 4 ng/mL were readily detected, while after 1 hour incubation, the limit of detection was approximately 1 ng/mL, and with a much improved assay window. Incubation times longer than one hour showed a slight improvement on assay performance.
