Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to
worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting
immunostaining in relation to complex human pathologies.
TCR Screening Services
Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding.
Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".
This ELISA kit recognizes the pro form of NPY by specifically detecting the C-flanking peptide of NPY (CPON). PCross Reactivity: This ELISA kit shows no cross-reactivity with any of the cytokines tested: Ghrelin, Nesfatin, Angiotensin II and APC
LS-F10 is a 96-well enzyme-linked immunosorbent assay (ELISA) for the Quantitative detection of Human Neuropeptide Y / NPY in samples of Cell Culture Supernatants and Serum. It is based upon a Competitive EIA assay principle and can be used to detect levels of Neuropeptide Y / NPY as low as 0.1 nanograms per millilter.
Cell Culture Supernatants, Serum
Colorimetric - 450nm (TMB)
0.1 - 1000 ng/ml
Intra-Assay: CV<10% Inter-Assay: CV<15%
Due to their limited shelf life, LSBio ELISA kits are not typically stocked as finished goods. Upon receipt of an order each kit is assembled and tested to ensure that it meets specifications before shipping. Minor changes may occur to the Range, Sensitivity, and Precision. In the event of a significant change the order would be confirmed with the customer before shipping ELISA kit lot numbers reflect the date of final assembly and testing for each specific kit rather than a bulk manufactured lot. All kits are tested to confirm that they fall within their defined Inter- and Intra- assay coefficient of variation.

Standard, Biotinylated Neuropeptide Y peptide, and Positive Control should be stored at -20°C after arrival. Avoid multiple freeze-thaws. The remaining kit components may be stored at 4°C. Opened Microplate Wells and antibody (Item N) may be stored for up to 1 month at 2° to 8°C. Return unused wells to the pouch containing desiccant pack and reseal along entire edge. If stored in this manner, Lifespan warranties this kit for 6 months from the date of shipment.

Neuropeptide Y / NPY is a neuropeptide that is widely expressed in the central nervous system and influences many physiological processes, including cortical excitability, stress response, food intake, circadian rhythms, and cardiovascular function. The neuropeptide functions through G protein-coupled receptors to inhibit adenylyl cyclase, activate mitogen-activated protein kinase (MAPK), regulate intracellular calcium levels, and activate potassium channels.
