Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate SUMO1 in samples. An antibody specific for SUMO1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anySUMO1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for SUMO1 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of SUMO1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:Small ubiquitin-related modifier 1 is a member of the SUMO protein family. It functions in a manner similar to ubiquitin in that it is bound to target proteins as part of a post-translational modification system. However, unlike ubiquitin which targets proteins for degradation, this protein is involved in a variety of cellular processes, such as nuclear transport, transcriptional regulation, apoptosis, and protein stability. It is not active until the last four amino acids of the carboxy-terminus have been cleaved off. Several pseudogenes have been reported for this gene. Alternate transcriptional splice variants encoding different isoforms have been characterized.Sequence analysis of the corresponding gene, termed UBL1, revealed that the gene encodes a 101-amino acid polypeptide with homology to ubiquitin and other ubiquitin-like proteins.
