Isotyping Kits – Get Results in Less than 3 Minutes!

Antagen Biosciences, Inc. is a Boston-based antibody development company. Antagen biosciences is a company founded and run by scientists, with a goal to benefit the scientific community. Antagen excels in glyco-engineering of mammalian cell lines for large-scale manufacture of antibodies for research and therapy. Using the proprietary “Toggle-In” technology, Antagen has also generated stable CHO cell lines expressing tumor antigens or immune receptors/ligands that are available to the research community.

While Antagen is developing therapeutic antibodies for patients with cancer, autoimmune and infectious diseases, the company also strives to serve the scientific community, and strengthen their research alliance through better products and services. Antagen scientists have developed rapid tests in lateral flow immunoassay (LFIA).

Lentiviral Titration

Rapid lateral flow immunoassay based titration device for fast and accurate lentivirus titres estimation. This is a crucial step for scientists using lentivirus as a gene delivery tool for basic research or for CAR-T therapy. Their second-generation LentiTitre cassette has 4 lanes that allow sample to be compared side-by-side with lentivirus standards with known titres. Results can be obtained in as little as 5 min, compared to days by the conventional infection method.

Aditionaly, Antagen’s antibody isotyping XpressCards for mouse, rat, hamster and human antibody isotyping have the most extensive product variants to suit customer needs in the current market. Crisp, clear bands appear in as little as 2-5 min, saving tremendous time and hassles for researchers when compared with using the conventional methods such as ELISA.

Mouse Antibody Isotyping  

5-minute lateral flow assay with ELISA sensitivity determines monoclonal antibody class and subclass

Rat Antibody Isotyping

5-minute determination of 6 Rat Ig heavy chain isotypes and 2 light chain subclasses

Hamster Antibody Isotyping

5-minute determination of hamster IgG1/2/3 isotypes and κ light chain

Cell lines

CHO cells with expression of hCNTFR.

Protein Expression system

Shortens stable cell lines development time with increased target proteins expression yield
