A 160 kDa complex of four protein molecules, consists of a dimer formed by a 25 kDa protein connected by two disulfide bonds, and three other proteins of 10, 30 and 70 kDa, respectively. It was isolated and analyzed on an SDS-PAGE gel without DTT in the gel loading dye. Which one of the following options would represent the SDS-PAGE profile?
1
Four bands corresponding to 10, 30, 50 and 70 kDa
2
Four bands corresponding to 10, 25, 30 and 70 kDa
3
One band corresponding to 160 kDa
4
Two bands corresponding to 50 kDa and 110 kDa
