Single B cell antibody cloning and sequencing has become popular for antibody discovery, especially for those difficult to obtain. After antigen specific single B cell sorting, the single B cells can be directly used for antibody seqencing or cultured for 2 weeks before antibody sequencing. Single B cell sequencing by next generation sequencing (NGS) including nanopore sequencing has been successfully applied to single B cell antibody technologies.
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.
Syd Labs has extensive experience with making DNA constructs for Fc fusion protein production, expressing and purifying a number of Fc fusion proteins from microgram to kilogram scales in mammalian cells, such as CHO and HEK 293 cells. With improved DNA construction system and fully optimized secretion signal and linker sequences, Syd Labs can efficiently complete a project from DNA construction and transient production of Fc fusion proteins in CHO and HEK 293 cells, to Fc fusion protein purification. N-term or C-term of Fc fusions of peptides and proteins in secreted form and multiple Fc backbone are available upon request.
