Antibody Preparation

Antibody Preparation

We have professional technical platforms, state-of-art instrumentation and elaborate product catalog. Experienced scientists will perform fusion, screening and culturing to ensure high quality at each step of the process; instruments will be operated and managed exclusively by well-trained staff to prevent cross-contamination between samples, minimize misoperation occurrence, and ensure normal operation of instruments. In terms of antibody preparation, we also provide a detailed product catalog, from which you can browse our data and select desirable antibodies.

Technical Platform

Methods that we are now providing for antibody preparation mainly consist of hybridoma preparation and single cell sequencing. Hybridoma technique is a conventional preparatory approach characterized by immortalized stable clones secreting antigen-specific antibody, and is thus well received by general antibody R&D staff. However, it has drawbacks, i.e. long cycle and genetic heterogeneity. Recently, a new star – single cell sequencing technique – has emerged in antibody screening field, as one of the most favored methods for modern researchers. It is neat and revolutionary, and it integrates multiple disciplines such as cell biology, molecular biology and bioinformatics.

In addition, what makes Biocytogen antibody preparation unique is the RenMab mice. Use of an antibody obtained by immunization of RenMab mice allows scientists to skip the humanization process of murine antibodies and obtain fully human antibodies against desired targets in one step, helping you carry out preclinical trials in advance.

 

Hybridoma Preparation

Based on classical hybridoma technique, this platform optimizes and overcomes greatly technical drawbacks of the conventional technique including low throughout, long time consumption and complicated operation, and establishes a characteristic Biocytogen in vivo pharmacodynamic screening system for animals, which, while keeping the advantages of conventional hybridoma technique, overcomes greatly its disadvantages. Using our unique screening method, one can obtain high purity hybridoma cells with fewer impurity peaks yet good affinity.

Antibody-Discovery-Hybridoma-Preparation

Single Cell Sequencing

Hybridoma cells are fast proliferating and genetically unstable, consequently the finally harvested cells are unable to secrete antigen-targeting antibody, hampering antibody yield. Biocytogen antibody discovery platform employs advanced single cell sequencing technique to add a unique tag sequence to each cell via a microfluid chip. By one-time cell bank construction, paired V-region sequences of many cells can be obtained. And compared with other methods, it has a simple workflow and is able to obtain quickly human or mouse V-region sequence just at single cell level.

Hybridoma Screening

ClonePix2

Heading layer

Automated screening process of ClonePix2 system enables more clones to be screened in a shorter time. Based on expression level of clone-secreted antibody, ClonePix2 sorts clones automatically, thereby enabling users to select high-expression clones. Culturing cells with semisolid medium enables harvest of a single clone of hybridoma or CHO-K1 cells. It is simple and convenient to operate, capable of avoiding shortcomings such as time-consuming limiting dilution and few positive clones, while the selection does not affect cell viability and proliferation capacity.
