NCAM, as a member of the immunoglobulin superfamily of adhesion molecules is characterized by several immunoglobulin (Ig)-like domains. The extracellular part of NCAM consists of five of these Ig domains and two fibronectin type III homology regions. NCAM is encoded by a single copy gene composed of 26 exons. However, at least 20-30 distinct isoforms can be generated by alternative splicing and by posttranslational modifications, such as sialylation. During sialylation, polysialic acid (PSA) carbohydrates are attached to the extracellular part of NCAM. Through its extracellular region, NCAM mediates homophilic interactions. In addition, NCAM can also undergo heterophilic interactions by binding extracellular matrix components, such as laminin, or other cell adhesion molecules, such as integrins. NCAM is expressed on most neuroectodermal derived cell lines, tissues and neoplasm such as retinoblastoma, medulloblastoma, astrocytomas and neuroblastoma.

The CD28.2 antibody reacts with human CD28, a 44 kDa type I surface glycoprotein which acts as a co-stimulatory receptor in support of the T cell receptor (TCR). CD28 exists as a homodimer with specificity for two known ligands, known as B7-1 (CD80) and B7-2 (CD86), which are expressed on activated B cells and antigen-presenting cells. These ligands trigger CD28 signaling in concert with TCR activation to drive T cell proliferation, induce high-level expression of IL-2, impart resistance to apoptosis, and enhance T cell cytotoxicity. The interaction / co-stimulatory signaling between the B7 ligands and CD28 provides crucial communication between T cells and B cells or APCs to coordinate the adaptive immune response. Other members of the CD28 family of receptors include CTLA-4 (CD152), PD-1 (CD279), ICOS and BTLA.

PMA (Phorbol-12-Myristate-13-Acetate) is a diester of phorbol and is a tumor promoting compound extracted from croton oil. It is a reversible, highly potent protein kinase C (PKC) activator in vitro and in vivo at nM concentrations. PMA’s effects on PKC are attributed to its similarity to diacylgylerol, a natural activator of PKC.
PMA activates Ca2+- ATPase and potentiates forskolin-induced cAMP formation. It has been shown to inhibit apoptosis induced by the Fas antigen, but PMA induces apoptosis in HL-60 promyelocytic leukemia cells.
Potent tumor promoter; activates protein kinase C in vivo and in vitro.
Store at -20 °C. Protect from light.
