Identification of Immunoglobulin Gene Sequences from a Small Read Number of mRNA-Seq Using Hybridomas.

ABSTRACT: Identification of immunoglobulin genes in hybridomas is essential for producing antibodies for research and clinical applications. A couple of methods such as RACE and degenerative PCR have been developed for determination of the Igh and Igl/Igk coding sequences (CDSs) but it has been difficult to process a number of hybridomas both with accuracy and rapidness. Here, we propose a new strategy for antibody sequence determination by mRNA-seq of hybridomas. We demonstrated that hybridomas highly expressed the Igh and Igl/Igk genes and that de novo transcriptome assembly using mRNA-seq data enabled identification of the CDS of both Igh and Igl/Igk accurately. Furthermore, we estimated that only 30,000 sequenced reads are required to identify immunoglobulin sequences from four different hybrido
