SingleB® Hybridoma Protein Expression

Hybridoma Antibody Gene Sequencing

Hybridoma cells are prone to contamination, gene loss, poor cell status and even death during preservation, which will affect the quality of antibodies produced. The antibody gene in hybridoma cells was extracted and sequenced to obtain the corresponding nucleotide sequence, so as to facilitate the stable expression and production of exogenous antibodies in the later stage.

DetaiBio has the full-length mRNA sequencing platform and Failsafe ® Pseudogene Elimination technology, which can provide rapid and reliable hybridoma antibody gene sequencing services. Based on RACE (Rapid Amplification of cDNA Ends) technology, this service can accurately sequence the variable region or full length of the antibody. The sequencing range covers mice, rats, rabbits, goats and other species. At the same time, DetaiBio also has a mature antibody expression platform, which can express, purify and verify the obtained antibody genes.
