PRODUCT INFORMATION

  • Product Overview
  • Recombinant human IL-4 is produced in P. Pichia and having a molecular mass of approximately 30kDa.
  • Specificity
  • Measured in a cell proliferation assay using a human factor-dependent cell line, TF-1. The specific activity shall be not less than 1×107IU/mg.
  • Endotoxin
  • Less than 0.1ng/ug (1 IEU/ug) determined by LAL test.
  • Purity
  • ≥97%, as determined by SDS-PAGE and HPLC method.
  • Storage
  • Lyophilized samples are stable for greater than six months from date of receipt at -20oC to -70oC. Upon reconstitution, this cytokine can be stored under sterile conditions at 2-8oC for one month or at -20oC to -70oC in a manual defrost freezer for three months without detectable loss of activity. Aliquot to avoid repeated freeze-thaw cycles.
  • Reconstitution
  • It is recommended to reconstitute the lyophilized rHuIL-4 in sterile 18MΩ-H2O containing at least 0.1% human serum albumin or bovine serum albumin to prepare a stock solution of no less than 5μg/ml of the cytokine.
  • Recombinant Human Interleukin-4
    Crystal structure of human IL-4(2INT).

BACKGROUND

  • Antigen Description
  • Interleukin 4 is a pleiotropic cytokine produced by activated T cells, mast cells, and basophils. It was initially identified as a B cell differentiation factor (BCDF), as well as a B cell stimulatory factor (BSF1). Subsequent to the molecular cloning and expression of both human and mouse IL-4, numerous other functions have been described on B cells as well as other hematopoietic and nonhematopoietic cells, including T lymphocytes, monocytes, macrophages, mast cells, myeloid and erythroid progenitors, fibroblasts, endothelial cells, etc. IL-4 exhibits anti-tumor effects both in vivo and in vitro.
