20000 cells per hybridoma clone are sufficient for cloning and sequencing the monoclonal antibody variable regions (both VH and VL) and full length. Welcome to challenge us with smaller number of clonal B cells or non-viable cells for hybridoma rescue.
Both Sanger sequencing-based and nanopore sequencing-based methods are available for antibody sequencing from hybridoma and clonal B cells. Sanger sequencing is labor intensive and time consuming so that it is difficult to reduce the cost for a large number of samples. However, nanopore sequencing can be used to reduce the cost signicantly, especially for a large number of samples.
