背景資料: Ang K1-3 is a proteolytic fragment of plasminogen containing the first three kringle structures. A specific inhibitor of endothelial cell growth and angiogenesis. More active relative to kringles 1-4. Ang K1-3 reduces endothelial cell proliferation and acts as a potent inhibitor of angiogenesis and tumor growth.

溶解建議: Sterile Filtered White lyophilized （freeze-dried） powder. Lyophilized from a 0.2um filtered concentrated （1.0mg/ml） solution in 20mM NaAc， pH5.5， 4% mannitol. We recommend to briefly centrifuge the vial 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 0.1-1.0 mg/ml. Stock solutions should be apportioned into working aliquots and stored at <-20°C. Further dilutions should be made in appropriate buffered solutions.

保存建議: The lyophilized Angiostatin K1-3 is stable for several weeks at 2-8℃， but should be kept at -20℃ for long term storage， preferably desiccated. Upon reconstitution， the preparation is stable for up to one week at 2-8℃. For maximal stability， apportion the reconstituted preparation into working aliquots and store at -20℃ to -70℃. Avoid repeated freeze/thaw cycles.

其他: ProSpec 是一家全球著名細(xì)胞因子蛋白生產(chǎn)和研發(fā)的公司，具有20多年的生產(chǎn)經(jīng)驗(yàn)，專注于蛋白（重組及合成）生產(chǎn)研發(fā)。我們的核心產(chǎn)品包括：干擾素、白介素、骨蛋白、腫瘤壞死因子、成纖維生長(zhǎng)因子、瘦素、干細(xì)胞因子、催乳素、表皮生長(zhǎng)因子、胰島素樣生長(zhǎng)因子、神經(jīng)生長(zhǎng)因子、集落刺激因子、激素、酶、病毒抗原以及各種重組蛋白等。領(lǐng)先的生產(chǎn)工藝和規(guī)模使其可以提供毫克到克級(jí)蛋白，價(jià)格優(yōu)于同類公司。絕大部分產(chǎn)品是天然成熟型蛋白，而不含有標(biāo)簽蛋白。考慮到大部分研究者希望能更靈活地配制蛋白溶液，ProSpec-Tany絕大部分產(chǎn)品沒(méi)有添加保護(hù)劑或鹽，這就對(duì)工藝提出了更高的要求。同時(shí)，ProSpec-Tany絕大部分產(chǎn)品為凍干粉，因此易于運(yùn)輸和保存。
