乳白蛋白

乳腺特异性人α-乳白蛋白真核表达载体的构建

Construction of mamary gland expression vector with human alpha lactalbumin gene

而这些热处理过程不可避免地会导致乳清蛋白主要功能性组分α-乳白蛋白、β-乳球蛋白和乳铁蛋白等发生变性，其变性程度在很大程度上依赖于热处理的时间和温度。

The heat treatment during processing these products will inevitably denature the major components of whey protein , such as bovine α - lactalbumin , β - lactoglobulin , lactoferrin , and so on . The degree of denaturation depends on the temperature and heat time .

本文采用HPLC和SDS-PAGE法研究UHT牛奶中的α-乳白蛋白成分。

The concentration of α - lactalbumin was analyzed by HPLC and SDS-PAGE in this paper .

本文利用SDS-PAGE电泳结合凝胶成像分析测定了乳饮料中的乳蛋白种类、相对含量及α-乳白蛋白（α-LA）和β-乳球蛋白（β-LG）的含量。

The composition and content of the milk drink were determined by SDS-PAGE associated with gel image analysis in this paper .

α-乳白蛋白在UHT奶中的应用研究

Study of HPLC and SDS-PAGE on α - Lactalbumin Analysis in UHT Milk

结合HPLC和SDS-PAGE法测得UHT牛奶中α-乳白蛋白的含量为1.98mg/mL。

The concentration of α - lactalbumin in UHT milk was 116mg / mL , which was determined by combing HPLC and SDS-PAGE .

人α-乳白蛋白基因YAC作为HSA基因高效表达载体的研究

Studies of Human α - lactalbumin YAC as a High Level Expression Vector of HSA Gene

结果发现：①α乳白蛋白，β乳球蛋白，αS1酪蛋白和β酪蛋白都存在多态性；

The results were as follows : ( 1 ) There was a polymorphism on the loci of α lactalbumin ,β? lactoglobulin ,α S1 casein and β casein .

细胞毒性实验表明，油酸和亚油酸诱导α-乳白蛋白形成的聚集体对人肺癌细胞A549具有显著的、浓度依赖的毒性，而硬脂酸诱导的聚集则没有对该肿瘤细胞表现出明显毒性。

Cell viability experiments indicate the aggregates of apo-BLA induced by oleic acid and linoleic acid show significant dose-dependent cytotoxicity to human lung tumor cells of A549 but those induced by stearic acid have no toxicity to tumor cells .

根据报道含完整人α-乳白蛋白基因的YAC载体能指导外源基因的乳腺特异性高效表达，是生产动物乳腺生物反应器的理想表达载体。

It have been reported that the 210 kb yeast artificial chromosome ( YAC ) including the human a - lactalbumin gene could direct the transgene to express in a position-independent manner , therefore is an excellent expression vector to produce transgenic animal bioreactors .

驴乳属乳清蛋白性乳类，乳白蛋白和乳球蛋白的含量占蛋白质总量的60%以上；

Donkey milk has the character of lactoalbumin , the content of lactalbumin and lactoglobulin is over 60 % of total protein content .

牛乳中含有大量的蛋白质，其含量约为牛乳的3.3%&3.5%，主要有酪蛋白、乳白蛋白、乳球蛋白和一些具有重要生理功能的酶类，其中酪蛋白占78.8%。

Milk includes the massive protein , its content approximately for 3.3 - 3.5 % of all milk . Mainly have the casein , lactalbumin , lactoglobulin and some enzyme class has the important physiological function , casein account for 8.8 % .
