Recombinant Human Persephin Protein Summary

• Description: A disulfide-linked homodimer of two 96 amino acid polypeptide chains corresponding to Persephin Source: E. coli

  Uniprot ID: P06734

  Amino Acid Sequence: ALSGPCQLWS LTLSVAELGL GYASEEKVIF RYCAGSCPRG ARTQHGLALA RLQGQGRAHG GPCCRPTRYT DVAFLDDRHR WQRLPQLSAA ACGCGG

• Preparation Method: Novus' biologically active proteins are stringently purified to provide only the safest and most highly effective proteins available. This protein was expressed in E. coli, purified by HPLC, QC tested by SDS-PAGE and Western Blot and validated on appropriate cell lines for bioactivity. All HPLC and bioactivity data is provided for your assurance.
• Details of Functionality: Persephin Protein is 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 x 10^5 IU/mg.
• Source: E. coli
• Protein/Peptide Type: Recombinant Protein
• Gene: PSPN
• Purity: > 97 % pure by SDS-PAGE and HPLC
• Endotoxin Note: Less than 0.1 EU/ug of Persephin as determined by LAL method.

Applications/Dilutions

• Dilutions:
  • Bioactivity
  • SDS-Page
• Theoretical MW: 20.5 kDa.
  Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Packaging, Storage & Formulations

• Storage: Store at -20 to -70C as supplied. After reconstitution, store at 2 to 8C for 1 month and at -20 to -70C for long term storage. Avoid repeated freeze-thaw cycles.
• Buffer: Lyophilized from a 0.2 um filtered concentrated solution in PBS, pH 7.4.
• Preservative: No Preservative
• Concentration: LYOPH
• Purity: > 97 % pure by SDS-PAGE and HPLC
• Reconstitution Instructions: Recommended to centrifuge prior to opening. Reconstitute in 4 mM HCl to a concentration of 0.1-1.0mg/mL. Apportion stock solutions into working aliquots and store at <-20C.

Notes

This lyophilized preparation is stable at 2-8 degrees C, but should be kept at -20 degrees C for long term storage, preferably desiccated. Upon reconstitution, the preparation is most stable at -20 to -80 degrees C, and can be stored for one week at 2-8 degrees C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 degrees C to -80 degrees C. Avoid repeated freeze/thaw cycles.

Background

Persephin belongs to the GDNF ligand subfamily of the TGF-beta superfamily. It promotes the survival and growth of central dopaminergic and motor neurons, and also is involved in kidney development. But persephin does not support survival of peripheral neurons.
