  • 产品描述：
    Ovalbumin is a native protein with full length. This protein is purified from chicken egg white. Its purity was determined by SDS-PAGE and reached up to 95%. It is presented the mass molecule around 45 kDa visualized on the gel. It has been validated in ELISA, WB and SDS-PAGE applications.
    Ovalbumin (OVA) is the main protein found in egg white proteins (EWP), which has good functionality, particularly foaming and gelling properties. OVA is a globular protein containing 385 amino acid residues, 1 disulphide bond, and 4 free sulphydryl groups. Ovalbumin displays sequence and three-dimensional homology to the serpin superfamily, but unlike most serpins it is not a serine protease inhibitor. Although it is presumed to be a storage protein, the function of ovalbumin is still unknown.

■ 常见问题解答
Q:

我买了CSB-NP004301C 卵清蛋白，今天解冻后发现溶液中有很多絮凝剂(可见的白色块状物)。我不确定这是污染还是蛋白质从溶液中流失了。 I purchased Ovalbumin and upon thawing it today noticed that there is a lot of flocculant (visible white chunks) in the solution. I'm not sure if it's contamination or if the protein crashed out of solution

A:
建议客户先离心取上清进行浓度检测和SDS-PAGE看下吧，若未降解，客户可以先用于实验检测；若蛋白不符合客户实验使用，我们这边年后对库存进行复溶检测，给客户重新补发一批；
Q:

I am looking for EndoGrade® Endotoxin-free Ovalbumin. Can you let me know if your protein Ovalbumin Protein - CSB-NP004301C – 1g is a good alternative, do you have tested the level of endotoxin? I need that the protein will be free of endotoxin or ≤ 1EU/mg.

A:
Thanks for your inquiry.
Code: CSB-NP004301C
Name: ovalbumin
We haven't removed endotoxin for this native protein at present. If you have demand for endotoxin level, please kindly remark when placing your order.
We could perform endotoxin removal , and guarantee the endotoxin level ≤ 1EU/ug.
