Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate PTCH1 in samples. An antibody specific for PTCH1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPTCH1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PTCH1 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 PTCH1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:PTCH1 encodes a member of the patched gene family. The encoded protein is the receptor for sonic hedgehog, a secreted molecule implicated in the formation of embryonic structures and in tumorigenesis. This gene functions as a tumor suppressor.
Mutations of this gene have been associated with nevoid basal cell carcinoma syndrome, esophageal squamous cell carcinoma, trichoepitheliomas, transitional cell carcinomas of the bladder, as well as holoprosencephaly. Alternative splicing results in multiple transcript variants encoding different isoforms. Additional splice variants have been described, but their full length sequences and biological validity cannot be determined currently.
