Q: About Protein Electrophoresis


 

Choose the correct electrical  migration of the proteins A,B,C and D in an electric field, knowing that the buffer solution in which are diluted the proteins has a pH of 6,4 and the isoelectric points of the proteins are:

 

 A = 5.2;  B = 6.4; C = 7.0; D = 9.2

 

a)     A will migrate to the positive pole, B will not migrate and C and D will migrate to the negative pole.

 

b)     A will migrate to the negative pole, B will not migrate and C and D will migrate to the positive pole.

 

c)      A and B will migrate to the negative pole and C and D will migrate to the positive pole

 

d)     A and B will migrate to the positive pole and C and D will migrate to the negative pole

 

e)     A will migrate to the negative pole, B and C will not migrate and D will migrate to the positive pole.
