碱性磷酸酶同功酶碱性磷酸酶同功酶(ALP)在体内分布范围很广,各组织中ALP活性依次为小肠粘膜～胎盘>肾>骨>肝～肺～脾。在肠粘膜细胞主要分布于细胞微绒毛上,肾脏中在近曲小管的刷状缘上,肝中主要见于毛细胆管,骨中主要存在于肥大的软骨细胞、成骨细胞乃至骨细胞中。根据来自各脏器ALP的理化性质不同,通过电 Alkaline phosphatase isoenzyme Alkaline phosphatase isoenzyme (ALP) in vivo distribution of a wide range of organizations, ALP activity in turn the small intestine mucosa ~ placenta> kidney> bone> liver ~ lung ~ spleen. In the intestinal mucosal cells are mainly distributed in the microvilli on the brush in the proximal tubule of the kidney, the liver mainly found in the bile duct, mainly in hypertrophic chondrocytes, osteoblasts and even osteocytes. According to the physical and chemical properties of ALP from various organs, through electricity
