OBJECTIVE To prepare monoclonal antibodies (mAbs) against human brain-derived neurotrophic factor (BDNF). METHODS BALB/C mice were immunized with purified BDNF protein in conjunction with acid-treated Salmonella (antigen:thallus=1:5), and mAbs were subsequently derived by hybridoma technique. RESULTS Three hybridoma cell lines secreting anti-BDNF mAbs were obtained, designated as B1, B2 and 4D1 respectively and all categorized into IgG1 subtype. The titers of the mAbs in the ascitic fluid of the rats ranged from 1x10(6) to 1x10(5), and their relative affinities were B2>B1>4D1. CONCLUSIONS mAbs against BDNF are successfully prepared, which can be instrumental for further study of the expression and distribution of BDNF in vivo, and the detection of BDNF produced by genetic engineering.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon

D019208 Brain-Derived Neurotrophic Factor A member of the nerve growth factor family of trophic factors. In the brain BDNF has a trophic action on retinal, cholinergic, and dopaminergic neurons, and in the peripheral nervous system it acts on both motor and sensory neurons.
