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.

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".

CD81 antibody was raised against oCI-LY8 cells aggregated by 5A6 (another CD81 antibody).
Recognizes human CD81, a 26kD cell surface antigen also known as TAPA-1, and a member of the tetraspanin family. CD81 is widely expressed on human leucocytes and appears to be involved in a variety of cellular leucocytes including activation, proliferation and differentiation. Is a potent CD81 reagent, induces homotypic adhesion and has powerful anti-proliferative effects.
Flow Cytometry: Use 10 ul of the suggested working dilution to label 10^6 cells in 100 ul. Method sheets are available on request.
PBS, pH 7.4, 0.09% Sodium Azide
Store at 4°C or -20°C. Avoid freeze-thaw cycles. Store undiluted.
