产品说明(Description)
Recombinant Human Leukemia Inhibitory Factor is produced by our E.coli expression system and the target gene encoding Ser23-Phe202 is expressed.
Accession #: P15018
Known as: Leukemia Inhibitory Factor; LIF; Differentiation-Stimulating Factor; D Factor; Melanoma-Derived LPL Inhibitor; MLPLI; Emfilermin; LIF; HILDA
制剂（Formulation）
Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.
质量控制（Quality Control）
Purity: Greater than 95% as determined by reducing SDS-PAGE.
Endotoxin: Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.
Bioactivity: Measured in a cell proliferation assay using TF‑1 human erythroleukemic cells.The ED50 for this effect is 25-150 pg/ml.
复溶（Reconstitution）
Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in distilled water.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
保存（Storage）
Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20°C for 3 months.
背景（Background）
Leukemia Inhibitory Factor (LIF) is a lymphoid factor that promotes long-term maintenance of embryonic stem cells by suppressing spontaneous differentiation. LIF has a number of other activities including cholinergic neuron differentiation, control of stem cell pluripotency, bone and fat metabolism, mitogenesis of certain factor dependent cell lines and promotion of megakaryocyte production in vivo. Human and murine mature LIF exhibit a 78% sequence identity at the amino acid level. Human LIF is equally active on human and mouse cells. Murine LIF is approximately 1000 fold less active on human cells than human LIF.

文献和实验Construction of Recombinant Human Cytomegalovirus
The use of reverse genetics to generate recombinant viruses allows the researcher to investigate the exact functional significance of particular viral genes during the virus life cycle, by means of their deletion or modification in the viral
amplification reaction. This chapter will focus on the preparation and the use of the 26plex assay with DNA samples for the purpose of human identification.
Delivery of Recombinant Adenoviruses to Human Saphenous Vein
The human saphenous vein is the most commonly used conduit for coronary artery bypass grafting owing to its ready availability, ease of harvesting, and favorable surgical handling (1 ). However, it suffers from a progressive decline
