SFRS4 Colorimetric Cell-Based ELISA

A Cell-Based ELISA Kit from Assay Genie designed for the precise detection of SFRS4 levels in cell lysates and cell culture supernatants. The colorimetric assay is read at 450 nm and is intended for use with adherent cells, with reactivity confirmed for human and mouse samples.

SFRS4, also known as Serine/Arginine-Rich Splicing Factor 4, is a protein involved in mRNA processing and alternative splicing, with roles in regulating gene expression and protein diversity. The kit provides a lysate-free, high-throughput workflow with a user-friendly protocol, suited to cell and molecular biology research. Qualitative determination of SFRS4 is achieved through an indirect ELISA format, with an anti-GAPDH monoclonal antibody included for internal normalization and an optional Crystal Violet whole-cell staining method for adjusting results to cell density.

Classified within the Epigenetics and Nuclear Signaling research area, the kit is stored at 4°C with a stated stability of 6 months and has a dynamic range of > 5000 cells.
