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".
Human recombinant C5a is as active as that of serum derived C5a based on enzyme release assay of myeloperoxidase. The current lot of ED50 = 1.36 nmolar.
Less than 0.1 ng/µg of protein.
Reconstitute in ice-cold water containing 2.5 mg/ml BSA to 1.0 mg/ml. The solution should be aliquoted and immediately stored at -70°C for future use. Freeze/thaw will result in some loss of activity.
Store at -20°C. Avoid freeze-thaw cycles.

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.
