||Recombinant Rat Tropic 1808 produced inE.coliis a single non-glycosylated polypeptide chain containing 285 amino acids and having a molecular mass of approximately 29.1 kDa.
||Rat Tropic 1808 is a candidate chemotropic factor induced by nerve injury. Tpc1808 protein, similar to NGF, could promote the expression of NF-H in a time-dependent manner. Tpc1808 is the gene related to promotion of nerve growth, and both the Tpc1808 gene and the Tpc1808 recombinant protein up-regulate the expression of NF-H in PC12 cells.
||>95% by SDS-PAGE and HPLC analyses.
||Lyophilized from a 0.2μm filtered concentrated (1mg/ml) solution in 1×PBS, pH 7.4.
||Less than 1EU/μg of rRaTPC1808 as determined by LAL method.
||We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/ml. Stock solutions should be apportioned into working aliquots and stored at <-20°C. Further dilutions should be made in appropriate buffered solutions.
||This lyophilized preparation is stable for several weeks at 2-8°C, but should be kept at -20°C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8°C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20°C to -70°C. Avoid repeated freeze/thaw cycles.
