Forward primer for galectin-1 geneGRP3: CTG GGATCC ATG GCT TGT GGT CTG GTC (BamH I site is bold and underlined) Reverse primer for galectin-1 geneGRP4: ACGC CTCGAC TCA GTC AAA GGC CAC ACA (SaI I site is bold and underlined). Mutagenesis in Galectin-1 In the case of internal mutations, the primers listed were used in conjunction with the 5' and 3' primers (GRP3 and GRP4), to make two, overlapping galectin-1 cDNA fragments, which then were annealed and extended to create galectin-1 cDNA with the intended substitution. In the case of substitutions near the ends of the molecule, a modified version of GRP 3 or 4 was used, in conjunction with the other, normal primer, for conventional PCR amplification of the cDNA.
