2003 OCT 1 - (NewsRx.com & NewsRx.net) -- Researchers have reported the expression of a prototypic anti-colorectal cancer polyclonal antibody library in mammalian cells.
"We describe the production of a prototypic polyclonal antibody library (PCAL), a standardized mixture of full-length IgG polyclonal antibodies for which the genes are available. The PCAL was generated by mass transfer of heavy and light chain variable region gene pairs, selected for binding to human colorectal cancer cells, from a Fab phage display vector to a mammalian IgG expression vector," scientists in the United States report.
"Following transfection of the IgG vector library into Sp2/0 myeloma cells, clones were characterized for IgG expression and binding to the colorectal cancer cells by ELISA, and for diversity by DNA fingerprinting, nucleotide sequencing, and immunoblot analysis," stated Liyan Chen and colleagues at Boston University. "The results showed that 76-84% of the library clones produce IgG and of those 72-79% bind antigen. Furthermore, ...
