SRM 927f 血清總(zong)蛋(dan)白(bai)臨床(chuang)分(fen)析(xi)

NIST SRM 927f  牛血清白蛋(dan)白(bai)（總(zong)蛋(dan)白(bai)）標準參(can)考物質

英文名(ming)稱(cheng)：Bovine Serum Albumin (7 % Solution) (Total Protein Standard)

品(pin)牌(pai)：美國(guo)NIST標準物(wu)質(zhi)

Storage: SRM 927f  牛血清白蛋(dan)白(bai) is supplied to the user in sealed ampoules. The SRM should be stored in a refrigerator at atemperature between 2 °C and 8 °C. The ampoules should not be frozen because of possible breakage of ampoulesduring the thawing process

.Instructions for Use: Once an ampoule is opened, the solution should be used promptly. Any unused solution inopened ampoules should be discarded.

Preparation of Dilutions: Protein solutions of lower concentration may be prepared by transferring the appropriatealiquot to a volumetric flask and diluting to volume. Diluents are not furnished with the SRM; an aqueoussodium chloride diluent, such as a solution having a concentration of 0.15 mol/L, may be used. Caution should betaken when performing dilutions greater than 100-fold due to the potential for protein loss (possibly due to proteinabsorption on laboratory equipment).

Inappropriate Uses: SRM 927f  牛血清白蛋(dan)白(bai) is not intended to be used as a standard for dye-binding tests as the dye-bindingcharacteristics of BSA will likely be dissimilar to other proteins being assayed. Additionally, this SRM is not intendedfor checking pre-calibrated refractometers, for immunochemical methods, or as an additive for bilirubinstandardization.
