Intended Uses: Sandwich enzyme-linked immune-sorbent assay for the determination of human ProGRP in serum, plasma, cell culture supernatants or tissue homogenate.
Principle of the Assay: This kit is based on sandwich enzyme-linked immune-sorbent assay technology. Anti-ProGRP monoclonal antibody is pre-coated onto 96-well plates. The standards and test samples are added to the wells and any ProGRP present is bound by the immobilized antibody. After washing away any unbound substances, the HRP conjugated anti-ProGRP monoclonal antibody is added to wells as detection antibody. Following a wash to remove any unbound antibody- enzyme reagent, the TMB substrates are added to visualize HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changes into yellow after adding stop solution. The density of yellow is proportional to the ProGRP amount of sample captured in plate. The O.D. absorbance is read at 450nm in a microplate reader, and then the concentration of ProGRP can be calculated.
Background: Progastrin-releasing peptide (proGRP) is a recently identified biomarker of small cell lung cancer (SCLC). Plasma proGRP level could be a useful monitoring biomarker for subjects with SCLC and the initial level may help with SCLC tumor staging. ProGRP was highly expressed in NCI-H446 cells and xenograft tissue. It could be used as a marker for quality control in sample processing and storage in biobanks. Korse CM1 et al study concluded that a high-risk proGRP level (more than twice the upper reference value) in subjects with well-differentiated neuroendocrine tumours, WDNETs is a strong indication for a primary tumour in the lung. Besides CgA, proGRP is a complementary tumour marker for monitoring in subjects with neuroendocrine tumour.

Product Notes
The ProGRP (Catalog #AAA490251) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. 90 min. incubation (37 degree C) + 60 min. (37 degree C) + 30 min. (37 degree C) = 3 hours total incubation time. Researchers should empirically determine the suitability of the ProGRP for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "ProGRP, ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
