Cooperation Seeking
Creative Biolabs is interested in collaborating with potential partners (include but not limit to major pharma or biotech firms) to further co-develop ADCC-enhanced CD20 antibody. For commercial partners interested in our ADCC-enhanced therapeutic antibodies, Creative Biolabs welcomes collaboration. Here are two ways for your choice, and please contact us for more details.
1) Collaborate with us and co-develop the programs from discovery phase to IND enabling. Costs will be shared.
2) Become a licensed candidate of our programs.
Looking forward to cooperating with you in the near future.
Official Name
MS4A1
Full Name
membrane spanning 4-domains A1
Background
This gene encodes a member of the membrane-spanning 4A gene family. Members of this nascent protein family are characterized by common structural features and similar intron/exon splice boundaries and display unique expression patterns among hematopoietic cells and nonlymphoid tissues. This gene encodes a B-lymphocyte surface molecule which plays a role in the development and differentiation of B-cells into plasma cells. This family member is localized to 11q12, among a cluster of family members. Alternative splicing of this gene results in two transcript variants which encode the same protein.

Antibody Isotype
IgG1
Antibody Clone
B-Ly1
Description
This clone was generated using a stable CHO cell line with the FUT8 knockout gene. It was 100% non-fucosylated. In an in vitro cell-based ADCC assay, the afucosylated antibody clone showed significantly higher ADCC activity compared to its wild type version. The binding affinity of the non-fucosylated Fc variant antibody to Fc receptor is much higher than than the same antibody with fucosylated Fc. Robust and stable production of qualitative fully non-fucosylated therapeutic antibodies is achieved.
Antibody Indication
