Maltotetraose 可以作為生物流體中酶聯(lián)測(cè)定淀粉酶活性的一個(gè)底物。Maltotetraose 具有口服活性,通過抑制 NF-κB 活性和減少 ICAM-1 表達(dá)來降低 TNF-α 誘導(dǎo)的炎癥反應(yīng)。Maltotetraose 還能抑制 PDGF 誘導(dǎo)的血管平滑肌細(xì)胞遷移和新生血管形成。此外,Maltotetraose 衍生物 可作為探針,通過靶向細(xì)菌麥芽糊精轉(zhuǎn)運(yùn)蛋白 (maltodextrin transporter) 以檢測(cè)細(xì)菌感染。Maltotetraose 具有良好的長(zhǎng)期安全性,有望用于動(dòng)脈硬化相關(guān)疾病研究。

生物活性

Maltotetraose can serve as a substrate for enzyme-linked assays to measure amylase activity in biological fluids. Maltotetraose has oral active, and reduces TNF-α-induced inflammatory responses by inhibiting NF-κB activity and decreasing ICAM-1 expression. Maltotetraose also inhibits PDGF-induced vascular smooth muscle cell migration and neovascularization. Additionally, Maltotetraose derivatives can function as probes for detecting bacterial infections by targeting the maltodextrin transporter. With good long-term safety, Maltotetraose holds promise for research in atherosclerosis-related diseases[1][2][3][4].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
