Santa Cruz Biotechnology offers a variety of gene silencing products to target lymphocyte signaling proteins via RNA interference (RNAi). Lymphocytes are agranulocytic leukocytes found in lymphatic tissue that are active in immune responses, including antibody production. There are two general categories of lymphocytes, namely the large granular lymphocytes and the small lymphocytes. To knockdown expression of lymphocyte signaling proteins, Santa Cruz Biotechnology offers siRNA, shRNA plasmid and shRNA lentiviral particles.
