Phospho p38 ELISA Kit

Microplate sandwich ELISA kit for phospho-p38 (pp38).

Thermo Scientific Phospho p38 ELISA Kits

Assay phosphorylated p38 ([pThr180/Tyr182] p38 MAP kinase, pp38) levels in cell lysates of human and mouse origin with our Thermo Scientific Phospho p38 ELISA Kit.

This phospho-p38 ELISA kit is an immunoassay for the quantitative determination of phosphorylated p38 ([pThr180/Tyr182] p38 MAP kinase, pp38) in cell lysates. A recombinant phospho-p38 standard is provided with the kit. The assay uses a monoclonal antibody to p38 precoated in a microplate to bind the phospho-p38 in the standards or sample. After a short incubation, the excess sample or standard is washed out of the plate and a phospho p38 detection antibody is added. This antibody binds to the phospho-p38 captured on the plate. After a short incubation, the excess antibody is washed out and secondary conjugate is added, which binds to the phospho-p38 detection antibody. Excess conjugate is washed out and TMB Substrate is added. After a short incubation, the enzyme reaction is stopped and the absorbance is read at 450nm. The measured optical density is directly proportional to the concentration of phospho-p38 in either standards or samples.


  • Target: phosphorylated p38 ([pThr180/Tyr182] p38 MAP kinase, phospho-p38); also called SAP kinase 2 (SAPK2)
  • Format: colorimetric ELISA (TMB substrate) in clear 96-well strip plate
  • Measurement: absorbance at 450nm minus absorbance at 550nm
  • Assay Range: 156 to 5000pg/mL
  • Sensitivity: < 52.1pg/mL
  • Precision: dependent upon sample type and level (see instructions)
  • Sample Types: cell lysates of human and mouse origin
  • Total Assay Time: 3 hours
  • Sample Size: 100μL
  • Specificity: no significant cross-reaction with non-phosphorylated p38, phospho-JNK, non-phosphorylated JNK, AKT, non-phosphoylated ERK, phospho-ERK.
