乳白蛋白

The polymerization of mono-substrate food proteins such as sodium caseinate, bovine serum albumin, glycinin and β-conglycinin,β-lactoglobulin and α-lactoalbumin by MTGase were studied by SDS-PAGE combined with the technique of imaging.

采用SDS-PAGE结合凝胶成像技术研究了还原状态下MTGase催化酪蛋白酸钠、牛血清蛋白、大豆球蛋白和β-伴豆球蛋白(β-conglycinin)、β-乳球蛋白和α-乳白蛋白等单底物蛋白聚合，结果表明：MTGase较易催化CN和BSA聚合，其次为glycinin，而β-伴豆球蛋白、β-LG和α-LA最不易。

Breast-feeding. Breast milk is mainly lactalbumin, easy digestion and absorption, so breast-fed infant stool soft.

母乳喂养。母乳中主要是乳白蛋白，容易消化吸收，所以吃母乳的婴儿大便较软。

A method was established for the determination of α-lactalbumin and β-lactoglobulin by SDS-PAGE electrophoresis. The quantified analysis of external standard calibration curves was used.

实验建立扫描定量测定乳清蛋白中α-乳白蛋白和β-乳球蛋白含量的SDS-PAGE电泳分析方法。

The cells were transfected with the eukaryotic expression vector αS1-LA-psv and the activity of β-galactosidase was detected after transfected from 24 h to 120 h. Human alpha lactalbumin was detected at 72 h after transfected too.

将构建的真核表达载体αS1-LA-psv 转染奶牛乳腺上皮细胞，培养24～120 h均检测到了β-半乳糖苷酶的表达；培养72 h检测到细胞中人α-乳白蛋白的表达，表达量约为

On the basis of the development of a new CE method for the analysis of α-lactalbumin,β-lactoglobulin A and β-lactoglobulin B, different concentrations of acetic acid and trichloroacetic acid for the removal of proteins in raw milk, infant formula A and B, and yogurt were investigated.

建立了毛细管电泳法分析α-乳白蛋白、β-乳球蛋白A及β-乳球蛋白B的方法，考察了不同浓度冰乙酸及三氯乙酸对原料奶、婴儿配方奶粉A和B及酸奶中蛋白的去除效果。

The average recoveries were 88.6%~86.3% with RSD 3.8%~4.2%. This method was simple and fast, it is a reliable means to measure the content of α-lactalbumin and β-lactoglobulin.

对乳清粉和奶粉的分析结果表明，SDS-PAGE电泳分析方法是一种简易、快速、准确测定α-乳白蛋白和β-乳球蛋白含量的方法。

It was subsequently realized that the product's bioactivity was dependent upon a critical concentration of three bioactive proteins contained in the milk serum: i.e., the thermolabiles—serum albumin, alpha lactalbumin and lactoferrin.

我们到后来才知道这产品的生理活性是来自乳浆所含的三种具有生理活性蛋白质的浓度，它们是：对温度敏感的血清白蛋白、α乳白蛋白及乳铁蛋白。

In the present study we investigated the effect of four weeks of treatment with a diet containing lactalbumin hydrolysate( LAH; Nestlé, Vevey, Switzerland) on the immune response of C3 H/ HeN mice.

本研究调查以水解乳白蛋白营养补充剂喂养小鼠四星期后对其免疫反应的影响。

The production of human alpha lactalbumin was 0.64 g/L approximately. The results indicate that the bovine mammary epithelial cell line have the ability of expressing exogenous gene, the 5′ flanking sequence of bovine αS1 casein gene has the effect of regulating gene expression specifically and the vector αS1-LA-psv which was constructed can coexpress alpha lactalbumin and β-galactosidase.

实验结果表明，建立的奶牛乳腺上皮细胞系具有外源基因表达活性，得到的牛αS1-酪蛋白5′调控序列能作为启动子指导外源基因的表达，构建的真核表达载体能在体外培养的牛乳腺上皮细胞中同时表达人α-乳白蛋白和β-半乳糖苷酶。

The results showed as follows: Five bands in SDS-PAGE, lactoferrin, bovine serum albulin, immunoglobulin G,β-lactoglobulin and α-lactoalbumin were detected.

结果表明：从SDS-PAGE电泳图谱上可见有5个清晰的条带，自上而下分别为乳铁蛋白、牛血清白蛋白、IgG重链、β-乳球蛋白和α-乳白蛋白。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
