Human TXNL4B ELISA Kit (HUFI05851)

The Assay Genie TXNL4B ELISA Kit enables quantitative detection of Thioredoxin-like 4B, a 13 kDa spliceosomal protein that forms part of the U5 small nuclear ribonucleoprotein (snRNP) complex essential for pre-mRNA splicing catalysis. Investigators in RNA biology, gene expression, and spliceosome assembly research apply this microplate-based kit to measure endogenous TXNL4B concentrations across human sample cohorts. Each kit contains all reagents necessary for the immunoassay workflow, including pre-coated wells, detection antibody, and standard diluents. Unopened components should be refrigerated and protected from light to maintain long-term stability, while reconstituted standards require aliquoting and freezing to prevent repeated freeze-thaw degradation. The format is supplied as a complete research use only kit intended for laboratory investigation of splicing factor abundance, not for clinical diagnostics.
