Nerve Growth Factor-2.5S from murine submaxillary gland

General description
Nerve growth factor (NGF) is produced by different cell types: structural, accessory, and immune cells. It belongs to the neurotrophin family of trophic factors.
Application
Nerve Growth Factor-2.5S from murine submaxillary gland has been used:
in Ham′s F-12 medium for performing growth cone collapse assay using dorsal root ganglions (DRGs)
as a media supplement in the “process compartment” for microfluidic chamber studies
to treat mid-luteal cells to study its effect on choline acetyltransferase (CHAT) expression
Biochem/physiol Actions
Nerve growth factor (NGF) is neurotrophic and maintains sympathetic and sensory neurons of the peripheral nervous system and forebrain cholinergic neurons. NGF promotes the development of neurite-like filaments from chick embryo dorsal root ganglia and rat PC12 pheochromocytoma cells. NGF may have a role in in vivo fetal development and nerve regeneration especially, after ischemic, surgical, or chemical injuries. NGF may also be associated with the central nervous system. It exhibits ameliorating effects against ulcers (human cutaneous, corneal ulcers, and pressure ulcers), glaucoma, maculopathy, and retinitis pigmentosa. NGF-2.5S is a type of NGF-b originally derived under dissociative conditions and often varies from NGF-b due to proteolysis arising during its purification.
Physical form
Lyophilized from a 0.2 μm filtered solution in sodium acetate buffer.
Analysis Note
The biological activity is measured using a 3-day MTT assay.
Other Notes
2.5S subunit of nerve growth factor-7S (NGF-7S) is essentially the β-subunit when isolated from male mouse submaxillary glands under initially dissociative conditions by a modification of the method of Bocchini and Angeletti.
