Human LIF (leukaemia inhibitory factor) suppresses the differentiation of murine embryonic stem cells (ESCs) and is widely used in ESC and induced pluripotent stem cell (iPSC) culture.
Qkine human LIF protein is a 17 kDa highly pure, bioactive, animal origin-free and carrier-protein free for reproducible results in stem cell culture.
- High purity human LIF protein (Uniprot: P15018)
- >98%, by SDS-PAGE quantitative densitometry
- 17 kDa
- Expressed in E. coli
- Animal origin-free (AOF) and carrier protein-free
- Manufactured in our Cambridge, UK laboratories
- Lyophilised from acetonitrile, TFA
- Resuspend in 10mM HCl at >100µg/mL (provided with protein and free of charge), prepare single use aliquots, add carrier protein if desired and store frozen at -20°C or -80°C
