Ovalbumin

Specification

Code	CSB-NP004301C
Product Type	Native Protein
Size	$800
Lead Time	2 weeks
Relevance	Storage protein of egg white. Lack protease inhibitory activity.
Image	(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.
Description	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.

Q&A

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.

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.

What is the concentration of the current batch of these product. Is there a concentration range for most batches

Very nice to receive your inquiry. CSB-NP004301C ovalbumin
Lead Time: In stock
Concentration of current batch: 10mg/ml
Concentration range for all batches: 10-20mg/ml
If your customer has special requirement for concentration, please kindly remark this info in your PO.

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.

Please centrifuge the sample and take the supernatant for concentration detection. SDS-PAGE analysis is also recommended. If it is not degraded, please use it for experimental testing; if the protein does not meet your experimental use, we will reconstitute the protein in stock for testing and supply you with the protein again.
