Human Glutaminyl-peptide cyclotransferase-like protein (QPCTL) ELISA Kit

From Assay Genie, this Sandwich ELISA Kit is intended for the quantitative detection of human Glutaminyl-peptide cyclotransferase-like protein (QPCTL) in research samples. It is reactive with human material and accepts serum, plasma, tissue homogenates, cell culture supernates, and other biological fluids, employing a colorimetric detection method.

Reported performance characteristics include a detection range of 0.156-10 ng/mL and a sensitivity of 0.078 ng/mL, with intra-assay precision of 4.5% CV and inter-assay precision of 8.7% CV. The kit shows broad linearity across serum, EDTA plasma, and heparin plasma at dilutions from 1:2 to 1:16, and recovery averaging 99% from serum and 101% from plasma. Specificity is reported for natural and recombinant human QPCTL, also referred to by the synonyms Golgi-resident glutaminyl-peptide cyclotransferase, isoQC, and gQC. QPCTL is a Golgi apparatus membrane protein (single-pass type I) responsible for the biosynthesis of pyroglutamyl peptides.
