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.
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".
LS-F2695 is a 96-well enzyme-linked immunosorbent assay (ELISA) for the Quantitative detection of Human KLK3 / PSA in samples of Cell Culture Supernatants, Plasma and Serum. It is based upon a Sandwich assay principle and can be used to detect levels of KLK3 / PSA as low as 10 picograms per milliliter.
This kit is for the detection of natural and recombinant human Kallikrein 3. No significant cross-reactivity or interference between Kallikrein 3 and analogs was observed.
Intended Sample Types
Cell Culture Supernatants, Plasma, Serum
Colorimetric - 450nm (TMB)
312 - 20000 pg/ml
Intra-Assay: CV%<6.3% Inter-Assay: CV%<7.8%
Short term: 4°C; Long term: see manual.
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.
Kallikreins are a subgroup of serine proteases having diverse physiological functions. Growing evidence suggests that many kallikreins are implicated in carcinogenesis and some have potential as novel cancer and other disease biomarkers. This gene is one of the fifteen kallikrein subfamily members located in a cluster on chromosome 19. Its protein product is a protease present in seminal plasma.
