설명

일반 설명

Monoclonal Anti-Splicing Factor SC-35 (mouse IgG1 isotype) is derived from the SC-35 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized RBF-DNJ mouse. Splicing component of 35 kDa (SC-35) is also termed as PR264. SC-35 displays a speckled distribution in the nucleus that co-localizes with small nuclear ribonucleoproteins (snRNPs), but unlike snRNPs, SC-35 does not give diffuse nuclear labeling.

Nuclear pre-mRNA splicing takes place in a multi-component structure termed a spliceosome. Major subunits of spliceosomes are U1, U2, U4/U6 and U5 small nuclear ribonucleoproteins (snRNP′s). In addition to the snRNP′s, a number of protein factors have been identified which are required for spliceosome assembly and splicing. For example, the protein factors U2AF, SF2 and SF3 are required for the binding of the U2 snRNP to the intron branch-point and for assembly of the pre-splicing complex. Two other non-snRNP splicing factors, SF2/ASF and SC-35 (splicing component of 35 kD, also termed PR264), are both required for the first step of splicing and spliceosome assembly. SF2/ASF and SC-35 are also involved in 5N splice site selection of alternatively spliced pre-mRNA′s.
The essential non-snRNP splicing factor SC-35 displays a speckled distribution in the nucleus that co-localizes with snRNPs, but unlike snRNPs, SC-35 does not give diffuse nuclear labelling. In the nucleus, snRNPs are concentrated in coiled bodies and in the speckled regions, whereas SC-35 is found in speckles but not in coiled bodies.

특이성

Recognizes a phospho-epitope on the non-snRNP (small nuclear ribonucleoprotein particles) factor SC-35. The antibody reacts with the splicing factor SC-35 and with the SC-35-related non-snRNP factor SF2/ASF. The antibody labels SC-35 as a speckled pattern in the nucleoplasm, excluding the nucleoli. Other uses include inhibition and depletion of splicing activity in nuclear extracts and immunoaffinity purification.
