Unequivocal Discrimination of Leucine and Isoleucine: Creative Biolabs Achieved an Unparalleled Breakthrough in De Novo Antibody Sequencing

New York, USA – November 7, 2019 – Creative Biolabs, a dynamic biotech company engaged in customized antibody development for decades, yesterday announced that the precise identification of leucine and isoleucine by mass spectrometry has been unprecedentedly achieved, advancing breakthrough science on protein/antibody sequencing in research, diagnostic, and therapeutic industries.

The discrimination of leucine and isoleucine has long been the key technical difficulties of de novo antibody sequencing. However, Creative Biolabs just took a massive leap forward into the new era of this field, with unchallenged ability to achieve 100% accuracy in antibody sequencing by precisely distinguishing between leucine and isoleucine, based on the proprietary Database Assisted Shotgun Sequencing (DASS) technology.

In the past, traditional de novo antibody sequencing using the Next-Generation Sequencing (NGS) technique could not precisely distinguish leucine and isoleucine due to their unspecific and random distribution, the same molecular mass, and similar chemical property. Researchers could only speculate the possible locations of leucine and isoleucine in an antibody sequence during analysis, which is time-consuming and uneconomical. Therefore, highly efficient and cost-effective sequencing technology is needed to overcome these conventional limits.

Through years of persistent efforts, scientists in Creative Biolabs successfully accomplished the mission impossible, being able to unequivocally distinguish the location of leucine and isoleucine, which enables a genuine sense of 100% accuracy in de novo antibody sequencing for superior functional analysis.

“A valuable breakthrough has never come easily. We all know how hard it is to confidently guarantee our clients 100% accurate results in an antibody sequencing project. This achievement really encouraged us a lot. In the past decade, our scientists have helped Creative Biolabs gain a good reputation through numerous successful cases and constant efforts. We are proud to provide antibody sequencing with 100% accuracy and satisfy our customers’ research needs,” said Dong H. Chen, the CSO of Creative Biolabs, “to precisely identify leucine and isoleucine is just one step along the path, but an important one.”
