CD19 Research Products CD19, a cell surface protein specific to B cells, has emerged as an effective immunotherapy target to treat B cell malignancies and autoimmune diseases. By leveraging monoclonal antibodies, chimeric antigen receptor (CAR) T cells and NK cells, or bispecific T cell/NK cell engagers (BiTEs/BiKEs), CD19-directed immunotherapies aim to selectively eliminate CD19-expressing cells. In cancer, these ther...

Bispecific Antibodies & BiTE® (Bispecific T-Cell Engager) Services   CD3/CD19 BiTE® - Mechanism of Action The CD3/CD19 BiTE® is a biopharmaceutical drug known as a Bi-specific T-cell engager for a second-line treatment for Philadelphia chromosome-negative relapsed or refractory acute lymphoblastic leukemia. It binds to CD19 on cancer cells (e.g. Raji cells) and CD3 on T cells simultaneously, thus bringing T lymphocytes closer to cancer cells expressing specific cancer ...

Bispecific Antibodies & BiTE® (Bispecific T-Cell Engager) Clinical & Therapeutic Research An antibody (Ab) containing two different antigen-binding sites within one molecule is known as a bispecific antibody (BsAb).  BsAb research has expanded greatly within the past ten years. To date, two BsAbs,  Blinatumomab   and Emicizumab, have been approved in the US and the EU, while a third BsAb, Catumaxomab, is already commercially available in the EU. Additionally, th...

CAR T-Cell Therapy Overview CAR-T is a cross of immunotherapy, gene therapy, and cellular therapy. Many successful immunotherapies are based on checkpoint inhibitors that block the mechanisms tumor cells use to hide from T cells. CAR-T immunotherapies go one step further by engineering T cells to enhance the immune response against a specific tumor antigen. CAR-T is a promising approach for cancer and other diseases, especially severe cancers that do not respond well to othe...

CAR-T Cell Therapy Engineering T cells using a chimeric antigen receptor (CAR) to boost specific immune cell killing has made significant progress in the treatment of some cancer types. CAR-T cell therapy may also have potential benefits beyond cancer treatment, including treatments for infectious and chronic inflammatory diseases such as hepatitis, HIV/AIDS, lupus, and arthritis. Companies are also investigating CAR-T cell therapy in organ transplantation to eliminate the n...

Cell Isolation Kits Our cell isolation kits allow for fast, simple, and efficient isolation of specific immune cell subsets. Optimized for the isolation of cells from normal human peripheral blood mononuclear cells (PBMCs), our kits use magnetic bead: antibody complexes to separate target antigen-expressing cells from heterogeneous cell populations. For positive selection kits, cells are incubated with the antibody:bead complexes and then p...

Primary Cells To support innovation across Immunology and other research areas, BPS Bioscience offers negatively selected, highly enriched CD4+ and CD8+ T cells, and ready-to-use Chimeric Antigen Receptor (CAR)-T cells such as anti-CD19 CAR, anti-BCMA CAR, and control T cells. Primary CAR-T cells, produced by high-titer lentiviral transduction of human primary CD4+ and CD8+ T cells, are used as a positive control in CAR-T cytotoxicity assays, in the design...

Conferences & Events Development of a Cell-Based Reporter Assay for Measuring ADAR1 Editing Activity for Drug Discovery and Cell Biology Research May 21, 2024 (8:00 AM PT, 11 AM ET) Adenosine Deaminase Acting on RNA (ADAR) enzymes perform adenosine to inosine base editing in RNA, particularly targeting adenosines located within a specific double-stranded stem-loop motif.  ADAR1 plays important roles in inflammation, autoimmune diseases, and cancer, and represents ...

ADC and Antibody-Based Cancer Therapies Antibody-based therapies, such as antibody-drug conjugates (ADCs) and multi-specific T cell engager molecules, provide a targeted approach to treating cancers.

Over 30 different tumor cell lines are availabl...

The Promise of NK Cell Therapeutics Introduction NK cells are the first line of defense against cancer and have been in the spotlight as a cancer therapy in the last decade. Their advantages versus T cells, such as their safety profile and not requiring MHC (Major Histocompatibility Complex)-antigen stimulation to become cytotoxic, have made NK cells attractive. However, as with T cells, the TME (tumor microenvironment) can suppress their activity, and infiltration into solid tumors is s...

The Power of Lentiviruses in Cell Engineering Introduction The ability to manipulate nucleic acids has been a key discovery that has driven research, and ultimately clinical applications, forward. It opened the door to study the impact of mutations in cellular models, dissect pathways, generate recombinant proteins and monoclonal antibodies, and is the basis of gene and cell therapy, continuing to lead to new discoveries and cure patients every day. The methods used to ...
