Selection Guide

  1. Application: Use carrier-free for sensitive bioassays (e.g., organoids, SPR).
  2. Expression System: HEK293/CHO for native glycosylation; E. coli for screening.
  3. Endotoxin: Target ≤0.1 EU/µg for immune cell assays; verify with CoA.
  4. Tag/Format: His for purification; Fc for avidity; lyophilized for storage.

Key Applications

T-cell/NK differentiation & activation; macrophage polarization
Stem cell maintenance and lineage commitment
Angiogenesis & wound-healing assays (VEGF/FGF/PDGF)
Inflammation & tumor microenvironment modeling

FAQs

Why choose carrier-free cytokines?

No stabilizing proteins (e.g., BSA), minimizing interference and enabling precise mass-based dosing.

Do mammalian-expressed proteins improve activity?

HEK293/CHO provide native PTMs and glycosylation, often improving receptor binding and stability vs. E. coli.

Recommended working concentrations?

Assay-dependent: IL-2 10–100 IU/mL; VEGF 5–50 ng/mL. Start with literature and titrate.

Storage & reconstitution tips

Use endotoxin-free buffers, avoid vortexing, aliquot to prevent freeze-thaw. Follow the lot-specific CoA.
