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".
Mouse (tested or 100% immunogen sequence identity)
IHC - Frozen (1:50)
Western blot (1:50)
Specificity and Use
Complement C4a antibody was raised against complement C4.
Recognizes an epitope on C4d. Reacts with intact C4, C4b, C4d.
Suitable for use in Western Blot, Immunoprecipitation and Immunohistochemistry. Western Blot (non-reducing conditions): 1:50. Immunoprecipitation: 1:10. immunohistochemistry (frozen): 1:50. Positive control, mouse spleen.
PBS, 0.02% sodium azide, 0.1% BSA.
+4°C or -20°C, Avoid repeated freezing and thawing.
Non-enzymatic component of C3 and C5 convertases and thus essential for the propagation of the classical complement pathway. Covalently binds to immunoglobulins and immune complexes and enhances the solubilization of immune aggregates and the clearance of IC through CR1 on erythrocytes.
