BirA Biotin-protein Ligase
Biotin-protein ligase (EC 6.3.4.15) activates biotin to form biotinyl 5' adenylate and transfers the biotin to biotin-accepting proteins. It also functions as a biotin operon repressor.
Recombinant Human BDNF
Human Brain-Derived Neurotrophic Factor (BDNF) is a member of the Nerve growth factor family. BDNF is induced by cortical neurons, and is necessary for survival of striatal neurons in the brain. During development, BDNF promotes the survival and differentiation of selected neuronal populations of the peripheral and central nervous systems.
Description
Human Brain-Derived Neurotrophic Factor (BDNF) is a member of the Nerve growth factor family. BDNF is induced by cortical neurons, and is necessary for survival of striatal neurons in the brain. During development, BDNF promotes the survival and differentiation of selected neuronal populations of the peripheral and central nervous systems. It participates in axonal growth, pathfinding and in the modulation of dendritic growth and morphology. It functions as the major regulator of synaptic transmission and plasticity at adult synapses in many regions of the CNS. The versatility of BDNF is emphasized by its contribution to a range of adaptive neuronal responses including long-term potentiation (LTP), long-term depression (LTD), certain forms of short-term synaptic plasticity, as well as homeostatic regulation of intrinsic neuronal excitability.

Streptavidin
Streptavidin is a non-glycosylated, 52.8 kDa, tetrameric bacterial protein isolated from Streptomyces avidinii with a very high affinity for biotin. Streptavidin-biotin bond is the strongest known non-covalent interaction with Kd ~10-15 M. Because streptavidin lacks any carbohydrate modification and has a near-neutral pI, it has the advantage of much lower nonspecific binding than avidin.
ApoA1
ApoA1 (Apolipoprotein A1) is synthesized in the liver and small intestine, and is the major protein component of high density lipoprotein (HDL) in the plasma. ApoA1 has a unique ability to capture and solubilize free cholesterol, and promotes cholesterol efflux from tissues to the liver for excretion. The process, called reverse cholesterol transport, is thought to inhibit atherogenesis.
Human Nicotinamide Phosphoribosyltransferase (NAMPT)
Human Nicotinamide Phosphoribosyltransferase (NAMPT) catalyzes the condensation of nicotinamide with 5-phosphoribosyl-1-pyrophosphate to yield nicotinamide mononucleotide, one step in the biosynthesis of nicotinamide adenine dinucleotide.
