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".

Specificity and Use
Complement C5a antibody was raised against human C5.
Human Complement C5/C5a
For neutralization of biological activity in vitro dilutions have to be made according to the amounts of C5/C5a to be inactivated. Before use in biological assays, the product must be filter sterilized and depending on the concentration to be used dialyzed against culture medium to remove the sodium azide added. Please inquire for availability of azide free solutions.

About Complement C5a
C5a is a protein fragment released from cleavage complement component C5 by protease C5-convertase into C5a and C5b fragments. C5b is important in late events of complement cascade, whereas C5a acts as highly inflammatory peptide. The origin of C5 is in the hepatocyte but its synthesis can also be found in macrophages that may cause local increase of C5a. C5a has chemotactic and anaphylatoxic properties, it is essential in the innate immunity but it is also linked with the adaptive immunity.
