Introduction
Cardiotrophin-like cytokine (CLC/ NNT-1) belongs to the IL-6 family of cytokines. All family members share the receptor subunit gp130, which belongs to the type I cytokine receptor superfamily. NNT1 is a trophic factor for motor neurons, a stimulator of ACTH release from corticotrophs, and an inducer of IgE synthesis and B cell proliferation. Cells expressing NNT-1 include embryonic muscle, lung epithelium, and mesenchyme. NNT1 binds to and activates the ILST/gp130 receptor.
Description
Neurotrophin-1 Human Recombinant (28-225) produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 199 amino acids and having a molecular mass of 22kDa.
The NNT-1 is purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
NNT-1 protein was lyophilized from a 0.2μm filtered solution in Acetonitrile and TFA.
Solubility
It is recommended to reconstitute the lyophilized NNT1 in sterile 18M-cm H2O not less than 0.5mg/ml, which can then be further diluted to other aqueous solutions.
Stability
Lyophilized Neurotrophin-1 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution NNT1 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
Purity
Greater than 95.0% as determined by SDS-PAGE.
