PCR amplification of antibody heavy chain variable region from hybridoma-1 cell line using alternate primers. Following total RNA isolation and cDNA synthesis, heavy chain VR region from hybridoma-1 cell line (Hybrid-1) was amplified by PCR using 5 alternate PCR primer sets (E-I) and each product resolved by electrophoresis on 1.2% agarose gel. SP2/0 and P3X = parental myeloma cell lines. MW = molecular weight. bp = base pairs. (-) no template control.
