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".
Reactivity is specific for phosphothreonine and minimal cross reactivity is observed against phosphoserine or phosphotyrosine
This monoclonal antibody reacts specifically with phosphothreonine and shows minimal reactivity by ELISA, and competitive ELISA, with phosphoserine or phosphotyrosine. The antibody reacts with free phosphothreonine, phosphothreonine conjugated to carriers such as thyroglobulin or BSA, as well as phosphothreonine in proteins of both unstimulated and stimulated cell lysates. Although not tested, this antibody is likely functional in RIA, flow cytometry, immunohistochemistry and immunoprecipitation. Phosphorylation of threonine residues is associated with many growth factors and oncogene protein kinases and is important for cell signaling in activation, proliferation and differentiation.

Anti-Phosphothreonine Antibody - Western Blot. Mab anti-phosphothreonine antibody (clone 18F6) is shown to detect threonine phosphorylation of proteins in a lysate from A431 cells stimulated with EGF. Separation is achieved under reducing conditions using a pre-cast 4-20% iGel from Gradipore, Inc. A 1:1000 dilution of Mab anti-phosphothreonine is used for 30 min followed by detection using a 1:2500 dilution of IRDye 800 conjugated Goat-a-Mouse IgG [H&L] ( and visualization using the Odyssey Infrared Imaging System developed by LI-COR. Other detection systems will yield similar results. IRDye is a trademark of LI-COR, Inc.
Enzyme-Linked Immunosorbent Assay
Anti-Phosphothreonine Antibody - ELISA. ELISA results of Mab anti-phosphothreonine antibody tested against BSA conjugates of pT, pY and pS. Each well was coated with 0.1 ug of conjugate. The starting dilution of antibody was 1:1000 and each point on the X-axis represents a 2-fold dilution. HRP conjugated Gt-a-Mouse IgG (H&L) and TMB substrate were used for detection.
