Specifications for Mouse IL-3 IS

Overview

IL-3 IS stands for interleukin 3 "Improved Sequence". Mouse IL-3 IS is a recombinant protein optimized for use in cell culture, differentiation studies, and functional assays.

Applications

Mouse IL-3 IS can be used for a variety of applications, including:
  • As cell culture supplement to maintain hematopoietic cells or cell lines, such as the pro-B lymphoid cell line BaF/3 or 32Dcl3 cells.
  • Induction of colony formation of hematopoietic progenitor cells in semi-solid medium, e.g. of highly purified Sca-1+/lin- cells.
  • Pre-stimulation of hematopoietic progenitor cells for retroviral transduction prior to bone marrow transplantation.
  • In vitro differentiation studies, e.g. of mast cells.

Detailed product information

Background information

Interleukin 3 (IL-3) is a hematopoietic growth factor which is produced mainly by activated T cells, but is also secreted by other cell types, including mast cells, eosinophils, and keratinocytes. The broad spectrum of biologic activities of IL-3 includes the stimulation of the proliferation and differentiation of immature pluripotent hematopoietic stem cells and various lineage-committed progenitor cells, leading to the production of most of the major blood cell types. In addition, IL-3 also affects the functional activity of mature mast cells, basophils, eosinophils, and macrophages.

  • We measure the biological activity of each batch of MACS Premium-Grade Cytokines and state the results in the Certificate of Analysis (CoA). Based on the lot-specific activity exact doses of active cytokine can be applied to cell culture experiments. This allows for reproducible cell culture conditions without the need for time-consuming lot-to-lot testing.

Quality description

Research-grade
cytokines are suitable for a wide variety of cell culture applications. They are sterile-filtered prior to lyophilization. Generally, endotoxin levels are <0.1 ng/μg (<1 EU/μg), and purities are >95%. The biological activity is tested in appropriate bioassays.
Premium-grade
cytokines offer the convenience of high and well-defined biological activities and allow exact unit dosing for demanding applications. The biological activity is determined after lyophilization and reconstitution, and normalized to WHO/NIBSC standards whenever available. In general, endotoxin levels are <0.01 ng/μg (<0.1 EU/μg), and purities are >97%. Lot-specific activities are stated in the Certificate of Analysis (www. miltenyibiotec.com/certificates).
