Mouse Eukaryotic Translation Initiation Factor 2 Alpha Kinase 3 (EIF2aK3) ELISA Kit

Quantitative measurement of murine EIF2AK3 supports research into unfolded protein response signaling and related stress pathways, and the Assay Genie Mouse EIF2AK3 ELISA Kit provides a two-antibody immunoassay platform for measuring eukaryotic translation initiation factor 2 alpha kinase 3 in mouse-derived research samples. EIF2AK3 (also known as PERK) is a serine/threonine kinase resident in the endoplasmic reticulum membrane that phosphorylates the alpha subunit of translation initiation factor 2, forming a central branch of the unfolded protein response and linking ER stress to translational control, apoptosis, and metabolic regulation. Quantifying EIF2AK3 levels supports work in stress biology, neurodegenerative disease models, metabolic disorder research, and immunology.

The procedure relies on capture antibodies pre-coated on a microplate, with bound analyte revealed through an enzyme-linked secondary antibody and a substrate reaction producing absorbance proportional to target concentration. The protocol accommodates tissue homogenates and other sample matrices prepared from mouse specimens, with a standard curve enabling translation of optical readings into concentration values. Plates are read on a standard microplate reader equipped with the wavelength appropriate for the chromogenic reagent supplied in the kit.

Each kit supplies reagents sufficient for 96 determinations in a single microplate, supporting medium-throughput screening campaigns. Unopened components should be kept refrigerated to preserve antibody and standard performance, with assay-specific handling steps described in the product manual. The Mouse EIF2AK3 ELISA Kit from Assay Genie is intended for research use only and is not validated for diagnostic applications.
