Separate plasma proteins by electrical charge?
electrophoresis
What is sds-page used for?
SDS - PAGE is apparently used to seperate proteins. The proteins are by nature different sizes. SDS works as a stabilizer by separating proteins according to similar forms.
Which process is the method by which a neutral object obtains an electrical charge?
induction
When the distance between two charges is three time far apart electrical force between the charge is?
Electrical forces are inversely proportional to the square of the distance separating the charges.
What is electrophoresis used for?
used to separate macromolecules, either nucleic acids or proteins, on the basis of size, electric charge, and other physical properties. Separating strands of DNA
How can you separate proteins from water?
The easiest way to separate proteins from bulk water is by using ultra-centrifugation. The "ultra" only means that these centrifuges are capable of applying a much greater force on a sample by spinning at a faster rotational velocity and/or by having a longer radius (or lever). Another method that is used, especially if there are fewer than some critical number of different proteins in a solution or suspension, is [gel] electrophoresis. In this method, which is also the one typically used to separate differently sized pieces of DNA, the protein solution or suspension is placed in a small well inside of a rectangular container containing a gelatinous material. A DC voltage is then applied across the two ends of the container. Because of their large size, proteins easily acquire an electrical charge. Proteins of different sizes and having different charges migrate through the gel at different rates when the voltage is applied, thus separating the different proteins (or pieces of DNA).
How do molecules get in and out of cell?
polar molecules are repelled by the cells electrical charge.
Is plasma a gas with an electrical charge?
Yes, a plasma is a gas with an electrical charge.
What kind of elicctcal charge do protons elictrons and nutrons have?
Protons have an electrical charge of +1. Neutrons have an electrical charge of 0. Electrons have an electrical charge of -1.
What electrical charge does a neutron contain?
A neutron carries no electrical charge
What is the electrical charge of aluminium?
The electrical charge of aluminum is +3.
What is proton electric charge?
A proton has a positive electrical charge and an electron has a negative electrical charge.
