About this Antibody
Name
Recombinant Human MIF (Recombinant Human Migration Inhibitor Factor; rHuMIF)；重組人移動抑制因子
Synonyms
EC 5.3.2.1; EC 5.3.3.12; GIFmacrophage migration inhibitory factor; GLIF; Glycosylation-inhibiting factor; L-dopachrome isomerase; L-dopachrome tautomerase; macrophage migration inhibitory factor (glycosylation-inhibiting factor); MMIF; Phenylpyruvate tautomerase
Purity
>97% by SDS-PAGE and HPLC analyses.
Biological Activity
Fully biologically active when compared to standard. The specific activity is determined by binding rhCD74 in a functional ELISA.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH7.4.
Endotoxin
Less than 1EU/μg of rHuMIF as determined by LAL method.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions.

Background
Migration Inhibitory Factor (MIF) is a secreted protein without a cleavable signal sequence and is secreted via a specialized, nonclassical pathway. It is secreted by macrophages upon stimulation by bacterial lipopolysaccharide (LPS), or by M.tuberculosis antigens. MIF consists of two α-helices and six β-strands, four of which form a β-sheet. The two remaining β-strands interact with other MIF molecules, creating a trimer. Structure-function studies suggest MIF is bifunctional with segregated topology. The N- and C-termini mediate enzyme activity (in theory). Phenylpyruvate tautomerase activity (enol-to-keto) has been demonstrated and is dependent upon Pro at position 1. Amino acids 50-65(a.a.) have also been suggested to contain thiol-protein oxidoreductase activity. MIF has proinflammatory cytokine activity centered around 49-65(a.a.). On fibroblasts, MIF induces, IL-1, IL-8 andmMP expression; on macrophages, MIF stimulates NO production and TNF-α release folllowing IFN-γ activation. MIF apparently acts through CD74 and CD44, likely in some form of trimeric interaction. Human MIF is active on mouse cells. Human MIF is 90%, 94%, 95%, and 90%a.a. identical to mouse, bovine, porcine and rat MIF, respectively.

保存條件: -20℃或更低溫度保存，至少一年有效。由于蛋白的每次凍融均會引起部分失活，所以**配制成相應濃度的儲存液后(請根據(jù)產品簡介中Reconstitution一欄的信息配制儲存液)，須分裝后-20℃或更低溫度凍存，以避免反復凍融。 注意事項: 由于有些塑料管壁對某些蛋白有較強的吸附作用，溶液中的蛋白很容易粘附在管壁上，并且粘附后的蛋白很難與管壁分離。而載體蛋白(Carrier protein，如0.1% BSA等)的主要作用是預先封閉塑料管壁上的蛋白結合位點，使細胞因子或重組蛋白不會粘附于管壁。所以一定要使用產品簡介中Reconstitution一欄的信息配制儲存液。 本產品**于專業(yè)人員的科學研究用，不得用于臨床診斷或**，不得用于食品或藥品，不得存放于普通住宅內。 為了您的**和健康，請穿實驗服并戴一次性手套操作。
