About this Antibody
Name
Recombinant Human TFF2 (Recombinant Human Trefoil Factor 2; rHuTFF2)；重組人三葉因子2
Synonyms
SML1; SP; Spasmolysin; Spasmolytic Polypeptide; SML1trefoil factor 2, SML1, human spasmolytic polypeptide (SP)10spasmolytic protein 1; SP; spasmolysin; Spasmolysin; Spasmolytic polypeptide; trefoil factor 2
Purity
>97% by SDS-PAGE and HPLC analyses.
Biological Activity
Fully biologically active when compared to standard. The ED50 as determined by a chemotaxis bioassay using human MCF-7 cells is less than 10ng/ml, corresponding to a specific activity of >1.0×105IU/mg.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in 20mM PB, pH7.4, 130mM NaCl.
Endotoxin
Less than 1EU/μg of rHuTFF2 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
Trefoil factor 2 encoded by the TFF2 gene in humans, belongs to the trefoil factor family that consists of three members named TFF1, TFF2 and TFF3. They are characterized by having at least one copy of the trefoil motif, a 40-amino acid domain that contains three conserved disulfides. The TFFs are stable secretory proteins expressed highly in the gastrointestinal tract (gastric mucosa). TFF2 can inhibit gastrointestinal motility and gastric acid secretion. Additionally, it functions as a structural component of gastric mucus, possibly by stabilizing glycoproteins in the mucus gel through interactions with carbohydrate side chains.

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(huì)引起部分失活，所以**配制成相應(yīng)濃度的儲(chǔ)存液后(請(qǐng)根據(jù)產(chǎn)品簡介中Reconstitution一欄的信息配制儲(chǔ)存液)，須分裝后-20℃或更低溫度凍存，以避免反復(fù)凍融。 注意事項(xiàng): 由于有些塑料管壁對(duì)某些蛋白有較強(qiáng)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(yù)先封閉塑料管壁上的蛋白結(jié)合位點(diǎn)，使細(xì)胞因子或重組蛋白不會(huì)粘附于管壁。所以一定要使用產(chǎn)品簡介中Reconstitution一欄的信息配制儲(chǔ)存液。 本產(chǎn)品**于專業(yè)人員的科學(xué)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(nèi)。 為了您的**和健康，請(qǐng)穿實(shí)驗(yàn)服并戴一次性手套操作。
