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...

CRISPR Services  CRISPR-Cas9 is a technique used for genome editing that is adapted from the bacteria’s antiviral immune response. Bacteria capture and store DNA fragments from invading viruses within a region of their genome, and these CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) guide sequences help detect and protect the bacteria from future infections. When the CRISPR guide sequences detect an invading virus or DNA whose sequence is complementary to the CR...

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...

Claudin-18: A Therapeutic Target in Oncology Claudins, a family of small tetraspan proteins expressed in a tissue or cell-specific manner, are major components of the multimeric protein architecture of tight junctions, which prevent ions or small molecules from passing freely between epithelial or endothelial cells. These proteins contain four transmembrane domains mainly responsible for interacting side-to-side with neighboring proteins. Two extracellular loops regulate p...

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...

Siglecs & Immunotherapy BPS has released a number of Siglec proteins and stable cell lines for studying immune-oncology and immune regulation . Cells of the immune system express a multitude of complex glycans on their surfaces, making them highly recognizable by diverse glycan-binding proteins. Siglecs (Sialic-acid-binding immunoglobulin-like lectins) are type I transmembrane proteins that bind to glycans containing sialic acid. These highly polymorphic proteins have very dist...

HVEM, LIGHT & BTLA: New Immunotherapy Target The checkpoint receptors  HVEM ,  LIGHT ,  CD160 , and  BTLA  are part of a complex network of overlapping receptor interactions that function in both immune stimulation and suppression 1 ,  2  .  This regulatory function has made them therapeutic targets for treatment of cancer, autoimmune diseases and allergies, and for improved methods of organ transplants.  While presenting opportunities for...
