产品描述: Human NGF-beta is a neurotrophic factor related to BDNF, NT-3 and NT-4. Human NGF-beta acts as a neurotrophic factor through its receptor beta-NGFR. This cytokine stimulates division and differentiation of sympathetic and embryonic sensory neurons, and is also involved in the growth and differentiation of B lymphocytes and B-cell survival. Human NGF-beta is a noncovalently disulfide-linked homodimer consisting of 121 amino acids with a MW of 2 x 13.6 kDa.
