, a MWCO of 12,000 to 14,000 is appropriate, whereas a MWCO of 3500, 2000, or even 1000 is appropriate for peptides. Most dialysis membranes are made of derivatives of cellulose. They come in a wide variety of MWCO values, ranging from 500 to 500,000

10kDa 干扰素γ诱导蛋白（IP10）在牛生物样本中的精确检测实验

加热使之融解。3. 标本溶血会影响最后检测结果，因此溶血标本不宜进行此项检测。试剂准备1.使用前将所有的试剂和标本缓慢均衡至室温 （18-25oC），试剂不能直接在 37oC 溶解。2.标准品 （冻干品）：每瓶标准品加入标准品稀释液 1 mL，盖好后室温静置大约 10 分钟，同时反复颠倒/搓动以助溶解，其浓度为 10ng/mL。准备 7 个稀释标准品的 EP 管，每个 EP 管中加入 500μL 的标准品稀释液，如图所示依次倍比稀释成 10ng/mL，5ng/mL，2.5ng/mL，1.25ng/mL
