This product has been discontinued.

The Ig-Primer Sets are designed for amplification of immunoglobulin (Ig) variable region cDNAs from human and mouse sources. Mammalian light- and heavy-chain Igs contain conserved regions adjacent to the hypervariable complementarity defining regions (CDRs). Appropriately designed oligonucleotide primer sets enable these regions to be specifically amplified using PCR (Larrick 1989, Jones 1991), after which the products may be sequenced directly or cloned. This powerful method enables rapid, precise analysis of hybridomas, myeloma cell progression and heterogeneity, idiotype networks, B-cell clonal ontogeny, and phylogenetic relationships.

In practice, total RNA is isolated from a B-cell source, such as peripheral blood, lymph node(s), spleen, or hybridoma, and first-strand cDNA is prepared using reverse transcriptase. The primer sets are then used in PCR to specifically amplify the variable regions of light- and heavy-chain cDNAs.
