Recombinant Human TPH2 Protein，His

TPH2

TPH2 Protein, an isozyme of tryptophan hydroxylase, is a member of the pterin-dependent aromatic acid hydroxylase family. TPH2 is selectively expressed only in the serotonergic neurons of the raphe nuclei and is a rate-limiting enzyme in the brain serotonin synthesis pathway. TPH2 plays a more prominent role in the 5-HT synthesis in the brain. Moreover, it is a key factor in maintaining normal serotonin transfer in the central nervous system. TPH2 Protein, Human (His) is the recombinant human-derived TPH2 protein, expressed by E. coli , with N-6*His labeled tag.

The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

In general, recombinant proteins are supplied as lyophilized powder and shipped at ambient temperature. For bulk packages, the proteins are provided as frozen liquid and shipped with blue ice, unless otherwise requested by the customer.
