Active Recombinant Human Interleukin 6 (Interferon, Beta 2)

• Cat.No.: IL6-128H
• Product Overview: Recombinant Human interleukin 6 (interferon, beta 2) protein sequence (containing the signal peptide sequence, and the mature human Interleukin 4 sequence) and was expressed in modifiedhuman 293 cells.

Specification

• Cat. No.: IL6-128H
• Description: IL-6 is a pleotropic cytokine that regulates the development, proliferation and maturation of a number of hematopoietic cells and is essential for the maturation of B cells into immunoglobulin-secreting cells.
• Source: Human 293 cells.
• Amino Acid Sequence: APVPPGEDSKDVAA PHRQPLTSSER IDKQIRYILDG ISALRKETCN KSNMCESSK EALAENNLN LPKMAEKDGCFQSGFNEETCLVKIITGLLEFEVY LEYLQNRFE SSE EQARAV QMST KVLIQFL QKKAKN LDAITTPDPTT NASLLTKLQA QNQWLQDMT T HLI L RSFK EFLQSSLRALRQM.
• Molecular Mass: IL-6 migrates as a broad band between 20 and 25 kDa in SDS-PAGE due to post-translation modifications, in particular glycosylation. This compares with the unmodified IL-6 that has a predicted molecular mass of 21.0kDa.
• PI: IL-6 separates into a number of isoforms with a pI between 5.5 and 7.2 in 2D PAGE due to post-translational modifications, in particular glycosylation. This compares with the unmodified IL-6 that has a predicted pI of 6.22.
• % Carbohydrate: Purified IL-6 consists of 0-20% carbohydrate by weight.
• Purity: >95%, as determined by SDS-PAGE and visualized by silver stain.
• Formulation: When reconstituted in 0.5 ml sterile phosphate-buffered saline, the solution will contain 1% human serum albumin (HSA) and 10% trehalose.
• Reconstitution: It is recommended that 0.5 ml of sterile phosphate-buffered saline be added to the vial.
• Storage: Lyophilized products should be stored at 2 to 8°C. Following reconstitution short-term storage at 4°C is recommended, and longer-term storage of aliquots at -18 to -20°C. Repeated freeze thawing is not recommended.
• Activity: The ED₅₀of IL-6 is typically 0.15 - 0.35 ng/ml as measured in a cell proliferation assay using a human growth factor-dependent TF-1 cell line.
