Overview
Recombinant Human GM-CSF (Granulocyte-Macrophage Colony-Stimulating Factor) is a biologically active cytokine that plays an essential role in the development and activation of granulocyte and macrophage progenitor cells. Produced in E. coli, this non-glycosylated form mimics the natural protein’s in vitro function, supporting immune cell expansion and functional assays in hematopoietic studies. GM-CSF is known to modulate the immune response and is often employed in research focused on hematologic diseases, immunotherapy, and stem cell biology.
Key Features and Benefits
- Validated Bioactivity: Induces TF-1 cell proliferation at low nanogram concentrations (ED₅₀ ≤ 0.5 ng/mL).
- Efficient Expression: Bacterial expression system ensures scalable, cost-effective production.
- High Purity & Low Endotoxin: >95% purity and endotoxin levels <1 EU/µg, ideal for sensitive cell culture work.
- Functional Versatility: Suitable for hematopoiesis, myeloid cell development, and immunological assays.
- Stable Form: Lyophilized format for long-term storage and flexible experimental planning.
Reconstitution Instructions
To ensure optimal performance:
- Brief Spin: Centrifuge vial to collect contents at the bottom.
- Reconstitute: Add sterile distilled water to achieve a final concentration of ≥0.1 mg/mL.
- Mix Gently: Swirl until completely dissolved; do not vortex.
- Application: Dilute in appropriate assay buffer or culture medium as required.
Quality Control (QC)
- Purity assessed via SDS-PAGE
- Endotoxin levels measured by LAL assay
- Functional activity validated in TF-1 cell proliferation assay
