应用
建议用于检测尿素酶活性。
生化/生理作用
尿素溶液主要用于蛋白质变性。它还可增加烃类溶解度,减少胶束形成。高浓度尿素溶液可导致β淀粉样蛋白寡聚体(16−22)失稳。
制备说明
将冷藏的 40% 尿素溶液加热至室温。在无菌条件下加入 5 mL 至 95 mL 无菌熔融尿素琼脂基质 (Christensen)。混匀,分装于无菌试管中。

P53 is critically important in preventing oncogenesis but its role in inflammation in general and in the function of inflammatory macrophages in particular is not clear. Here, we show that bone marrow-derived macrophages exhibit endogenous p53 activity, which is increased

Immortalized hepatocyte cell lines show only a weak resemblance to primary hepatocytes in terms of gene expression and function, limiting their value in predicting drug-induced liver injury (DILI). Furthermore, primary hepatocytes cultured on two-dimensional tissue culture plastic surfaces rapidly dedifferentiate

The impairment of hepatic metabolism due to liver injury has high systemic relevance. However, it is difficult to calculate the impairment of metabolic capacity from a specific pattern of liver damage with conventional techniques. We established an integrated metabolic spatial-temporal
