Tested Applications

• Positive WB detected in: HEK-293T cells, HEK-293 cells, PC-3 cells
• Positive IP detected in: HeLa cells
• Positive IHC detected in: human pancreas cancer tissue; Note: suggested antigen retrieval with TE buffer pH 9.0; (*) Alternatively, antigen retrieval may be performed with citrate buffer pH 6.0

Recommended dilution

• Western Blot (WB): WB : 1:2000-1:16000
• Immunoprecipitation (IP): IP : 0.5-4.0 ug for 1.0-3.0 mg of total protein lysate
• Immunohistochemistry (IHC): IHC : 1:20-1:200

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

SF3B4, also named as Pre-mRNA-splicing factor SF3b 49 kDa subunit, is a 424 amino acid protein, which belongs to the SF3B4 family. SF3B4 is a subunit of the splicing factor SF3B required for 'A' complex assembly formed by the stable binding of U2 snRNP to the branchpoint sequence (BPS) in pre-mRNA. SF3B4 has been found in complex 'B' and 'C' as well. Belongs also to the minor U12-dependent spliceosome, which is involved in the splicing of rare class of nuclear pre-mRNA intron. The calculated molecular weight of SF3B4 is 44 kDa. Based on its predicted molecular mass and the observed migration of the 50kDa cross-linked species on two-dimensional gels.(PMID: 9614130)
