Recombinant TIGIT Now Available!

New Ancell TIGIT-muIg binds to CD155 on U-937 cells and to recombinant CD155-muIg in EIA!   The TIGIT – CD155 regulatory pathway is emerging as an important element of immune function.  Studies using knockout mice demonstrate that this pathway is important in optimal NK effector cell function (activation and/or tolerance) (1) There is significant potential

CD268 in BCP-ALL

CD268 (BAFF-R, TNFRSF13C) is a significant marker for B Cell Precursor Acute Lymphoblastic Leukemia (BCP-ALL). Ancell clone ANC268.2 was used to phenotype patient samples.  Blocking the BAFF – BAFFR pathway may prove to be useful in treating BCP-ALL.  “TNFRSF13C (BAFFR) positive blasts persist after early treatment and at relapse in childhood B-cell precursor acute lymphoblastic

TIGIT – CD155 pathway

The TIGIT – CD155 regulatory pathway is emerging as an important element of immune function.  Studies using knockout mice demonstrate that this pathway is important in optimal NK effector cell function (activation and/or tolerance) (1) There is significant potential for the development of immunological drugs that could blockade this pathway, restoring anti-cancer immune response (2).

Nanoparticle based Flu vaccine shows promise in pig study

An Ohio research group tested the efficacy of inactivated Swine Influenza virus (SwlV) encapsulated in 200–300 nm diameter PLGA (poly lactic co-glycolic acid) microspheres. Pigs were immunized twice intranasaly.  While control pigs had fever for four days, treated pigs showed no clinical flu symptoms.  “Biodegradable nanoparticle delivery of inactivated swine influenza virus vaccine provides heterologous
