珠蛋白在机体内的浓度通常为0.3～2mg/ml,但在应急状态下可升至8mg/ml。珠蛋白有3种形式,球形Hp11、线状聚合体Hp21和环形聚合Hp22,在同一个体内只有一种形式存在。近年究发现,珠蛋白还有很多其他功能,如抑制前列腺合成、抑制凝集素诱导的淋巴细胞转化、促进血管生、促进Th1型 The concentration of globin in the body is usually 0.3 ~ 2mg / ml, but in emergency can be raised to 8mg / ml. There are three forms of globin, spherical Hp11, linear polymer Hp21 and circular polymerization Hp22, in the same body there is only one form. Recent studies have found that there are many other functions of globin, such as inhibition of prostate synthesis, inhibition of lectin-induced lymphocyte transformation, promote angiogenesis and promote Th1 type
