Peptides

SARS Peptides

Individual peptides for SARS-CoV-2 Spike glycoprotein. In order to study the specificity of cellular immune responses against SARS CoV-2 and potential immunity caused by other human Corona Viruses, Abcepta provides Spike peptide individually, as pools and in plate. These peptides can be used for antigen specific T-cell stimulation in T-cell assays or T-cell expansion.

Cell/Tissues/Lysates

Abcepta's portfolio of cell lines, tissues and lysates are drawn from a range of species and immortalized cell lines. All our cell lines and lysates are validated in key applications.

These tissue lysates can be used in applications such as SDS-PAGE and Western blotting. Whole cell lysates can be used as positive controls for applications such as ELISAs, immunoprecipitation (IP) and Western blotting. Obtaining high-quality whole cell lysates can be tedious as well as time consuming. Abcepta offers a comprehensive portfolio of whole cell lysates for research use. Browse our catalog to find the right whole cell lysate for your experiment.

Clonality	Monoclonal Antibody
Calculated MW	58849 Da

Gene ID	10946
Other Names	SF3A3
Dilution	WB~~1/500-1/1000
Format	Liquid

Name	SF3A3
Synonyms	SAP61
Function	Component of the 17S U2 SnRNP complex of the spliceosome, a large ribonucleoprotein complex that removes introns from transcribed pre-mRNAs (PubMed:10882114, PubMed:11533230, PubMed:32494006, PubMed:34822310, PubMed:8022796). The 17S U2 SnRNP complex (1) directly participates in early spliceosome assembly and (2) mediates recognition of the intron branch site during pre-mRNA splicing by promoting the selection of the pre-mRNA branch-site adenosine, the nucleophile for the first step of splicing (PubMed:10882114, PubMed:11533230, PubMed:32494006, PubMed:34822310). Within the 17S U2 SnRNP complex, SF3A3 is part of the SF3A subcomplex that contributes to the assembly of the 17S U2 snRNP, and the subsequent assembly of the pre-spliceosome 'E' complex and the pre-catalytic spliceosome 'A' complex (PubMed:10882114, PubMed:11533230). Involved in pre-mRNA splicing as a component of pre-catalytic spliceosome 'B' complexes (PubMed:29360106, PubMed:30315277).
