Recombinant Human PDYN (C-6His)(C812)
产品说明(Description)
Recombinant Human Proenkephalin-B is produced by our Mammalian expression system and the target gene encoding Asp21-Ala254 is expressed with a 6His tag at the C-terminus.
Accession #: P01213
Known as: ADCA; PENKB; SCA23; PDYN; Dynorphin B; Big Dyn
制剂(Formulation)
Lyophilized from a 0.2 μm filtered solution of 4mM HCl.
质量控制(Quality Control)
Purity: Greater than 95% as determined by reducing SDS-PAGE.
Endotoxin: Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.
复溶(Reconstitution)
Always centrifuge tubes before opening.Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100μg/ml.
Dissolve the lyophilized protein in distilled water.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
保存(Storage)
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20°C for 3 months.
背景(Background)
Proenkephalin-B(PDYN), belongs to the opioid neuropeptide precursor family. The N-terminal domain contains 6 conserved cysteines thought to be involved in disulfide bonding and/or processing. Leu-enkephalins, which is a type of Proenkephalin-B, compete with and mimic the effects of opiate drugs. They play a role in a number of physiologic functions, including pain perception and responses to stress. Dynorphin peptides differentially regulate the kappa opioid receptor. Dynorphin A has a typical opiod activity, it is 700 times more potent than Leu-enkephalin.
