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".
Recombinant hepatitis B virus ?€e?€ antigen produced in E.coli, is a 21kDa peptide showed on a 12% SDS-PAGE. The HBeAg sequence is derived from HBV adw2 and fused to 6xHis Tag.
Greater than 95% by SDS-PAGE
PBS, pH 7.4.

About HBV E Antigen / HBeAg
HBcAg (core antigen) is a hepatitis B viral protein. HBeAg is the extracellular form of HBcAg, hence why the presence of both are markers of viral replication, and antibodies to these antigens are markers of a decline in replication. Both HBeAg and HBcAg are made from the same reading frame, but HBeAg is secreted from cells and accumulates in serum as an immunologically distinct soluble antigen.
