After conducting SDS-PAGE, you will conduct a staining/destaining procedure, which allows for visual identification of the proteins in your gel. This procedure requires the following staining solution: Coomassie Blue staining solution: 0.1% Coomassie Blue dye (dry powder) in 50% methanol, 10% acetic acid. Required:
How to make 1 L of this solution?

Add 700mL of water.

Explanation:

The technique of separation known as the Sodium Dodecyl Sulfate Poly-Acrylamide Gel Electrophoresis in which its acronym is SDS- PAGE is a very important aspect of Chemistry and Biochemistry as the technique make use of molar mass when it work in seperating proteins.

From the question we have the following parameters or information:

Case 1=> 50% of methanol which is the same as saying 50mL in 100mL of water.

Case 2=> 0.1% Comasse Blue dye (dry powder) which is the same as saying 0.1g in 100mL of water.

Case 3=> 10% acetic acid is the same as saying 10mL in 100mL of water.

Adding the three together, we have ;

50mL in 100mL of water + 0.1g in 100mL of water + 10mL in 100mL of water.

The volume of water in the three = 100 mL + 100mL + 100mL = 300mL.

Therefore, there is need to add 700mL of water to make 1L.

That's 700mL of water + 300mL = 1000mL = 1L

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

hope it ,
