Human PSPN Protein

• Catalog Number: orb427951
• Category: Proteins
• Description: Recombinant of human PSPN protein
• Form/Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.
• Buffer/Preservatives: Lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4.
• Purity: Greater than 95.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
• Protein Sequence: ALSGPCQLWS LTLSVAELGL GYASEEKVIF RYCAGSCPRG ARTQHGLALA RLQGQGRAHG GPCCRPTRYT DVAFLDDRHR WQRLPQLSAA ACGCGG
• Application notes: Cytokines And Growth Factors
• Source: Escherichia Coli
• Biological Activity: 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 10ng/ml, corresponding to a specific activity of > 1.0 × 100,000 IU/mg.
• Solubility (25°C): It is recommended to reconstitute the lyophilized PSPN in 4mM HCl not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
• Storage: Stability: Lyophilized PSPN although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution PSPN 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
• Alternative names: Persephin, PSP, PSPN.
• Note: For research use only
• Expiration Date: 6 months from date of receipt.
