What is amino acids?
Western blotting test for this macromolecule.
What is proteins?
The order of amino acids is determined by this macromolecule
What is DNA?
The purpose of adding a secondary antibody is to...
What is to allow detection for the protein of interest?
In the picture below, this type of intermolecular force is the reason why these two are shaped like this.
What are Hydrogen Bonds?
what does SDS-Page to proteins?
Hint: 2-part answer from video.
What is denaturing them and covering them in negative charges?
The marker bands on the left of the picture are used in reference to helping determine this when the proteins are separated.

What is molecular weight?
This group is unique to amino acids. They determined ionic bonds, hydrophobic interactions (typically inside of structure), hydrophilic interactions (typically outside of structure), etc. all while driving folding.
What are the R-group (side-chain)?
Ionic bonds, hydrophobic/phillic interactions, Van Der Waals interactions, disulfide bonds, etc. all influence what structure?
hint: the last question talked about the importance.
What is tertiary structure?
This membrane is capable to bind large amounts of proteins. Its main function is to transfer proteins in the gel to the membrane.
What is a nitrocellulose membrane?

In this Western Blot, which antibodies look much more prominent than the other antibodies?
What is Cathepsin D?
