Biotin cadaverine free base ( N -(5-Aminopentyl)biotinamide) can be directly coupled to activated carboxylic acid groups without using an additional base. Also see biotin-X cadaverine free base.

An abundant secondary metabolite of ?9-THC

Neurotrophin-4 (NT-4) is a small secreted cytokine, and belongs to the Neurotrophin (NT) family, which also includes Brain Derived Neurotropic Factor (BDNF), Nerve Growth Factor (NGF), and NT-3. NT family members are all derived from similar sized protein precursors, composed of N-terminal...

Ghrelin is the first natural appetite stimulant found to be made outside the brain. It is one of a complex array of natural substances that carry messages between the brain and the digestive system. Secreted by specialized cells in the stomach and the upper part of the small intestine, ghrelin acts...

Tau is a microtubule-associated phosphoprotein (MAP), localized in neuronal axons. It promotes tubulin polymerization and stabilizes microtubules. Tau proteins constitute a family of six isoforms, which range from 352 to 441 amino acids. The tau variants differ from each other by the presence of...

KE00252 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The VEGF-C ELISA kit is to be used to detect and quantify protein levels of endogenous VEGF-C. The assay recognizes human VEGF-C. An antibody specific for VEGF-C has been pre-coated onto the microwells. The VEGF-C...

Extracellular adenosine mediates a multitude of biological effects, including wakefulness, antiarrythmia, bronchoconstriction and response to ischemia and oxidative stress. A family of four G-protein coupled adrenoceptors, A1, A2A, A2B and A3, is responsible for these effects. A3, which couples to...
