Supplier: ADVANCED BIOMATRIX, INC. MS
Description: Tropoelastin is the precursor to the elastin molecule. Elastin is found in many tissues of the body including the skin, arterial walls and ligaments. Elastin confers strength and elasticity to tissues and organs.

Tropoelastin is not normally available in its native state since it becomes cross-linked immediately after its synthesis by the cell, during its export into the extracellular matrix.

This tropoelastin is produced using recombinant production methods. The product is supplied as a sterile, lyophilized powder containing 1 mg per vial. A Certificate of Analysis is available with the purchase of each product.

Tropoelastin is typically used as a thin coating on tissue culture surfaces. Specific instructions are found in the Directions for Use. This product is generally used in vitro as a substrate scaffold to enhance cell attachment, adherence and proliferation.

Supplier: Enzo Life Sciences
Description: CD40 is a 45-50 kDa type I membrane protein and a member of the tumor necrosis factor (TNF) receptor superfamily. CD40 is also known as pb50 or CDW40.  CD40 is expressed primarily by professional antigen-presenting cells and it is also expressed on non-immune cell types. The CD40 expressed by professional antigen-presenting cells plays a critical role in co-stimulation and antigen-presenting cell activation in T cell-dependent immune responses. Signals generated through CD40 in B cells are anti-apoptotic. These signals are also required for T cell-dependent B cell activation and proliferation, isotype switching, up-regulation of costimulatory receptors, germinal center formation and memory generation. CD40 signal transduction is initiated by binding trimeric CD40 ligand (CD40L) which is found on the surface of activated T cells.  CD40 engages several signalling pathways in B cells and these include NF-kB, the mitogen-activated protein kinases p38 and c-Jun N-terminal kinase. The 62 amino acid cytoplasmic domain (CD40c) of CD40 contains two linear TNF-receptor associated factor (TRAF) binding domains. The membrane proximal site of CD40c binds TRAF6 and the membrane distal site binds TRAF1, 2 and 3. CD40c is thought to mediate the CD40-dependant signalling pathways by recruitment of TRAF to this multimerized domain. CD40 ligation has also been shown to stimulate iNOS expression, and therefore NO production, by activating NF-kB in IFN-g treated microglial cells. NO derived from microglia has been implicated in the damage of myelin-producing oligodendrocytes in demyelinating disorders like multiple sclerosis (MS) and neuronal death during Alzheimer’s disease and brain trauma. Increased CD40-CD40 ligation has been implicated in the pathogenesis of several autoimmune inflammatory diseases, such as MS, arthritis and insulin-dependant diabetes.
