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".
35.8 kDa. DTT-reduced protein migrates as 50-65 kDa due to glycosylation
HEK 293 Cells
Greater than 95% by SDS-PAGE
Measured by its binding ability in a functional ELISA. When rhCD55 is coated at 1 µg/ml (100 µl/well), the concentration of rhCD97 that produces 50% of the optimal binding response is found to be approximately 0.15-2.0 µg/ml.
Less than 1.0 EU/µg protein (determined by LAL method).
Lyophilized from PBS, pH 7.4, mannitol or trehalose
Centrifuge the vial before opening. Reconstitute in sterile PBS, pH 7.4 to 50 µg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 month. For extended storage, store at -20°C.
This protein recognizes C4b and C3b fragments that condense with cell-surface hydroxyl or amino groups when nascent C4b and C3b are locally generated during C4 and c3 activation. Interaction of daf with cell-associated C4b and C3b polypeptides interferes with their ability to catalyze the conversion of C2 and factor B to enzymatically active C2a and Bb and thereby prevents the formation of C4b2a and C3bBb, the amplification convertases of the complement cascade.
