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".
LS-F10890 is a 96-well enzyme-linked immunosorbent assay (ELISA) for the Quantitative detection of Human ASS1 / ASS in samples of Cell Culture Supernatants, Plasma, Serum and Tissue Homogenates. It is based upon a Sandwich assay principle and can be used to detect levels of ASS1 / ASS as low as 0.156 nanograms per millilter.
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.
Arginosuccinate synthetase catalyzes the penultimate step of the arginine biosynthetic pathway. There are approximately 10 to 14 ASS pseudogenes scattered across the human genome; the ASS gene located on chromosome 9 appears to be the only functional gene for argininosuccinate synthetase. The ASS primary transcript is subject to alternative splicing in the 5' non-coding region; a splice variant lacking exon 2 occurs in liver and fibroblast cells.
