Biotinylated Human LIF Protein, His Tag, Avi Tag (Avitag™)

内毒素:
Less than 1.0 EU per μg by the LAL method.

纯度:
>90% as determined by SDS-PAGE.

活性:
Measured by its binding ability in a functional ELISA. Immobilized Biotinylated Human LIF, His Tag, Avi Tag (Cat. No. LIF-H82E2) on SA-coated surface at 1 μg/mL (100 μL/well) can bind Human LIF R, Fc Tag (Cat. No. LIR-H4252) with a linear range of 1-31 ng/mL (QC tested).

产品背景:
Leukemia inhibitory factor, or LIF, an interleukin 6 class cytokine, is a protein in cells that affects cell growth and development.Leukemia Inhibitory Factor has several functions such as cholinergic neuron differentiation, control of stem cell pluripotency, bone & fat metabolism, mitogenesis of factor dependent cell lines & promotion of megakaryocyte production in vivo. Removal of LIF pushes stem cells toward differentiation, but they retain their proliferative potential or pluripotency. Therefore LIF is used in mouse embryonic stem cell culture. It is necessary to maintain the stem cells in an undifferentiated state, however genetic manipulation of embryonic stem cells allows for LIF independent growth, notably overexpression of the gene Nanog. LIF is not required for culture of human embryonic stem cells.

产品描述:
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag. The protein has a calculated MW of 23.4 kDa. The protein migrates as 37-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
