HCP Antibodies

Leverage Rockland’s 15+ years of success generating custom polyclonal host cell protein antibodies (HCP antibodies) to keep your biopharmaceutical development program meeting deadlines and moving efficiently.

Our comprehensive, fully customizable services cover all aspects of anti-HCP antibody generation, from antigen preparation and assay development to documentation and manufacturing, with an end-goal of creating a broad immune response as measured by a high percent of coverage on a 2D Western blot.

Whether you need support from start-to-finish or are only outsourcing small parts of the project, you can be confident when you partner with Rockland.

We use 1D SDS-PAGE followed by Western blot analysis on test and production bleeds to evaluate the host antibody-mediated immune response to HCP lysate.

We also evaluate HCP antibodies with 2D PAGE and Western blotting

We can also conduct 2D SDS-PAGE followed by Western blotting. 2D separation can deliver more complete insight into an anti-HCP antibody’s coverage of proteins in the host cell lysate than 1D SDS-PAGE and Western blotting
