Human SF3B4 ELISA Kit (HUFI06586)

SF3B4 (Splicing Factor 3b Subunit 4) is a core component of the U2 small nuclear ribonucleoprotein complex, essential for pre-mRNA spliceosome assembly and accurate branch-site recognition during splicing. This quantitative immunoassay kit from Assay Genie measures SF3B4 protein levels in human samples through a colorimetric readout, supporting research in RNA splicing biology, spliceosomopathies, and Nager acrofacial dysostosis where SF3B4 loss-of-function variants have been implicated.

Supplied as a 96 Assays kit intended for research use only, the assay accommodates standard microplate workflows and integrates with laboratory protocols investigating splicing factor expression, congenital craniofacial disorder mechanisms, and comparative profiling of spliceosomal components across human specimens. The protocol fits into routine immunology and molecular biology workflows, including studies comparing patient samples against healthy controls to characterize SF3B4 abundance in disease versus normal physiological states.
