• CAS Number: 9000-83-3
• Gene Name: IL5
• UniProt: P05113
• Expression Region: 20-134aa
• Organism: Homo sapiens
• Target Sequence: IPTEIPTSALVKETLALLSTHRTLLIANETLRIPVPVHKNHQLCTEEIFQGIGTLESQTVQGGTVERLFKNLSLIKKYIDGQKKKCGEERRRVNQFLDYLQEFLGVMNTEWIIES
• Tag: N-terminal hFc-Flag-tagged
• Source: Mammalian cell
• Field of Research: Immunology
• Assay Type: Developed Protein
• Relevance: Factor that induces terminal differentiation of late-developing B-cells to immunoglobulin secreting cells.
• Purity: Greater than 90% as determined by SDS-PAGE.
• Activity: Not Test
• Length: Full Length of Mature Protein
• Form: Liquid or Lyophilized powder
• Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
• Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
