Mouse LIF Protein, His Tag

分子别名(Synonym)

LIF,CDF,DIA,HILDA,MLPLI

表达区间及表达系统(Source)

Mouse LIF, His Tag (LIF-M5227) is expressed from human 293 cells (HEK293). It contains AA Ser 24 - Phe 203 (Accession # P09056-1).

Predicted N-terminus: Ser 24

蛋白结构(Molecular Characterization)

Online(Ser 24 - Phe 203) P09056-1

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 20.8 kDa. The protein migrates as 33-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

电泳(SDS-PAGE)

Mouse LIF, His Tag (Cat. No. LIF-M5227) SDS-PAGE gel

Mouse LIF, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.

背景(Background)

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.
