产品名称:Recombinant Human Persephin

氨基酸序列: ALSGPCQLWS LTLSVAELGL GYASEEKVIF RYCAGSCPRG ARTQHGLALA RLQGQGRAHG GPCCRPTRYT DVAFLDDRHR WQRLPQLSAA ACGCGG

Accession: <a href="http://www.uniprot.org/uniprot/P06734" target="_blank">P06734</a>

中文别名: Persephin蛋白

Gene IDs: <a href="http://www.ncbi.nlm.nih.gov/gene/2208" target="_blank">2208</a>

来源: Escherichia coli.

纯度: > 97 % by SDS-PAGE and HPLC analyses.

内毒素水平: Less than 0.1 EU/μg of Recombinant HumanPersephin as determined by LAL method.

活性: Fully biologically active when compared to standard. The ED₅₀ as determined by a cell proliferation assay using human TT medullary thyroid cancer cells is less than 10 ng/ml, corresponding to a specific activity of > 1.0 × 10⁵ IU/mg.

形态: Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.

溶解方法: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in 4 mM HCl 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.

储存/保存方法: This lyophilized preparation is stable 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.
