What is BN page?
Blue native PAGE (BN-PAGE) can be used for one-step isolation of protein complexes from biological membranes and total cell and tissue homogenates. It can also be used to determine native protein masses and oligomeric states and to identify physiological protein–protein interactions.
What is native gel electrophoresis?
What is a native gel? “Native” or “non-denaturing” gel electrophoresis is run in the absence of SDS. While in SDS-PAGE the electrophoretic mobility of proteins depends primarily on their molecular mass, in native PAGE the mobility depends on both the protein’s charge and its hydrodynamic size.
What is native SDS-PAGE?
SDS and native page are two types of polyacrylamide gel electrophoresis techniques used in Molecular Biology. The key difference between SDS Page and Native Page is the type of polyacrylamide gel used. In SDS Page a denaturing gel is used therefore, molecules are separated based on their molecular weight.
What are blue native gels?
What is Blue Native-PAGE? BN-PAGE or Blue Native Polyacrylamide Gel Electrophoresis is a common and inexpensive technique to resolve protein complexes by molecular weight while retaining their native structure through gel electrophoresis.
What does native PAGE tell you?
Nondenaturing PAGE, also called native-PAGE, separates proteins according to their mass/charge ratio. Two-dimensional (2D) PAGE separates proteins by native isoelectric point in the first dimension and by mass in the second dimension.
Why is SDS used in SDS-PAGE?
You may recognize it if you read the ingredients lists on your shampoo, soap, or toothpaste. The purpose of the SDS detergent is to take the protein from its native shape, which is basically a big glob, and open it up into a linear piece.
How much protein should I load on native gel?
Generally, the sample must contain 20 to 30 ng of each protein/µl for Coomassie staining, and at least 1 to 5 ng of each protein/µl for silver staining. Samples containing more than 2 µg/µl (Coomassie) or 100 ng/µl (silver) of each protein can overload the gel and distort results.
How do you store native PAGE gel?
Native PAGE gel storage. The natige PAGE gels can be stored up to 2-3 months in 7% acetic acid solution. In addtion, the gel should be sealed in packs. In dry conditon, if the gel is thicker than 1.0mm, it should be dried by gel drier.
What is native protein gel?
Native gel methods Native gels, also known as non-denaturing gels, analyze proteins that are still in their folded state. Thus, the electrophoretic mobility depends not only on the charge-to-mass ratio, but also on the physical shape and size of the protein.
Why is a protein electrophoresis test done?
The test separates proteins in the blood based on their electrical charge. The protein electrophoresis test is often used to find abnormal substances called M proteins. The presence of M proteins can be a sign of a type of cancer called myeloma, or multiple myeloma.
How long do polyacrylamide gels last?
If you store it in the way you described it, you can at least store it for 2-3 weeks. I have done that without problems. I normally soak the gel in the SDS running buffer using a paper towel & store at 4 degree C.
What is the percentage of gel used in native PAGE?
Native gel electrophoresis using Tris-Glycine Gels
| Recommended sample buffer | Tris-Glycine Native Sample Buffer |
|---|---|
| Available polyacrylamide concentrations | 6%, 8%, 10%, 12%, 14%, 16%, 4–12%, 4–20%, 8–16%, 10–20% |
| Available gel sizes | Mini: 8 cm x 8 cm (1.0 mm thick) Midi: 8 cm x 13 cm (1.0 mm thick) |
Is native PAGE denaturing?
Native Page uses non-denaturing gels and separates proteins based on their size, charge and the shape (3D conformation). A denaturing gel is used in SDS-page. A non – denaturing gel is used in the native page.

What is nativepage Novex?
The native PAGE gel system from Invitrogen is commercially known as the NativePAGE™ Novex® System. Options exist for gradient gels that are 3-12% gel or 4-16%; are all pre-cast. The gels come in either a 10-well or 15-well loading option.
What is the nativepage™ Novex® Bis-tris gel?
The NativePAGE™ Novex® Bis-Tris Gel is a 1.0 mm thick, 8 x 8 cm mini gel used for native (non-denaturing) gel electrophoresis of protein samples. The NativePAGE ™ Novex® Bis-Tris Gels are used with NativePAGE Running Buffers (see page 5) to produce a non-denaturing electrophoresis system operating at near neutral pH.
