New Express 35 Day Antibody Development

With United States Biological you do not have to wait for 80 days until the rabbit gives a good response. Their new technology speeds up the development of the immune response; in 35 days the animals give titers of specific antibodies (IgG's) which can be even higher than after 60-80 days of a standard (multiple injection) immunisation scheme.

Molecular Biology Services

Current services available to customers include polyclonal and monoclonal antibody production, cDNA and genomic library construction, library screening, custom cloning and expression, large-scale plasmid purification, protein expression, peptide synthesis and ELISA development.
