The protein, encoded by the DPP4 gene is an antigenic enzyme expressed on the surface of most cell types and is associated with immune regulation, signal transduction and apoptosis. It is an intrinsic membrane glycoprotein and a serine exopeptidase that cleaves X-proline dipeptides from the N-terminus of polypeptides.
It is a rather indiscriminate enzyme for which a diverse range of substrates are known. The substrates of CD26/DPPIV are proline(or alanine)-containing peptides and include growth factors, chemokines, neuropeptides, and vasoactive peptides. DPP4 plays a major role in glucose metabolism. It is responsible for the degradation of incretins such as GLP-1. Furthermore, it appears to work as a suppressor in the development of cancer and tumours.
The entire kit may be stored at -20°C for up to 1 year from the date of shipment. Avoid repeated freeze-thaw cycles. The kit may be stored at 4°C for up to 6 months. For extended storage, it is recommended to store at -80°C.

脂联素,也称为Acrp30,是脂肪细胞衍生的蛋白质,对代谢和炎症具有广泛的旁分泌和内分泌作用。它促进脂肪细胞分化,脂肪酸分解代谢和胰岛素敏感性,并且与肥胖症,2型糖尿病和动脉粥样硬化形成负相关。脂联素缔合成70 kDa非共价连接的三聚体,该三聚体被二硫键连接成中等分子量的六聚体。
从发货之日起,整个套件可在-20°C下最多保存1年。避免重复冻融循环。该试剂盒可在4°C下最多保存6个月。对于长时间存储,建议在-80°C下存储。
