Human FOXP1 ELISA Kit (HUFI07888)

FOXP1 (Forkhead box protein P1) is a member of the FOX family of winged-helix transcription factors. It is expressed in B and T lymphocytes, cardiac progenitors, and several neuronal populations, where it regulates genes controlling proliferation, differentiation, and survival. Aberrant FOXP1 expression has been documented in diffuse large B-cell lymphoma and MALT lymphoma, and heterozygous loss-of-function variants are linked to a neurodevelopmental syndrome characterized by intellectual disability, speech delay, and behavioral features.

This quantitative immunoassay from Assay Genie measures human FOXP1 protein in serum-derived or plasma-derived research specimens. The kit is supplied as a complete reagent set including pre-coated microplate wells, calibrated standards, biotinylated detection reagent, streptavidin-HRP conjugate, wash buffer, substrate solution, and stop solution, formatted for laboratory workflows handling multiple samples in parallel. Reagents should be equilibrated to room temperature before use, and the protocol accommodates standard plate-reader-based readouts. The kit is intended for research use only and is not validated for diagnostic procedures.

Researchers investigating lymphoma biology, cardiac development, or neural crest differentiation may use this kit alongside complementary methods such as western blot, immunohistochemistry, or flow cytometry to cross-validate findings. Because FOXP1 protein levels can be low in circulating specimens, careful handling — including prompt separation of plasma or serum and storage at low temperature with limited freeze-thaw cycles — helps preserve measurable protein. Each kit provides enough reagents for one full plate of determinations, packaged as a single-use format intended for the assays specified on the supplied certificate of analysis.
