Anti-Human NT-4

Purified Recombinant Human NT-4 (>98%)

This antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 containing 5.0% w/v trehalose with no calcium, magnesium, or preservatives present.

Lyophilized

The lyophilized antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for twelve months from date of receipt. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.

Immunohistochemistry: Suitable for use at concentration of 5-15 µg/mL.
Neutralization: Measured by its ability to neutralize NT‑4-induced proliferation in BaF‑TrKB‑BD mouse pro‑B cell line transfected with TrkB. The Neutralization Dose (ND₅₀) is typically 0.4-2 µg/mL in the presence of 40 ng/mL Recombinant Human NT‑4.

Rabbit Anti-Human Neurotrophin-4 (NT-4) recognizes Human NT-4. This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.

Neurotrophin 4 (NT-4) is a novel neurotrophic factor¹, the neurotrophins, that control survival and differentiation of vertebrate neurons. Several aspects distinguish NT-4 from other members of the neurotrophin family. It is the most divergent member and, in contrast to the other neurotrophins, its expression is ubiquitous and appears to be less influenced by environmental signals. NT-4 seems to have the unique requirement of binding to the low-affinity neurotrophin receptor for efficient signalling and retrograde transport in neurons.² NT-4 controls survival and differentiation of mammalian neurons. It signals predominantly through the TrkB receptor tyrosine kinase. Both NT-4/5 and brain-derived neurotrophic factor may be physiological survival factors for facial motor neurons and may serve as therapeutic agents for motor neuron disease.³
