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".
Streptococcus (tested or 100% immunogen sequence identity)
Specificity and Use
Streptococcus A antibody was raised against streptococcus Group A.
Recognizes Streptococcus Group A. Does not react with other Strep groups. No immunological cross-reactivity. However, there is potential non-specific reactivity with such organisms as group C Streptococcus and Staphylococcus due to the presence of protein A like proteins (Staphylococcus) and protein C like proteins (Streptococcus C) present on the intact surface of these bacteria. These proteins bind any immunoglobulin (including the FITC Conjugate) and therefore will appear to fluoresce (non-specifically).
Direct FA staining of target antigens in a permissive tissue culture system. Working dilution must be determined by the user for his or her application but a starting range of 1:10-1:50 is suggested. Acetone fixation of the antigen source is recommended prior to staining. Pre-block slide with 10% normal rabbit serum. The applications listed have been tested for the unconjugated form of this product. Other forms have not been tested.
