Fraction analysis of MICU2-NΔ84-CΔ28 in Ca2+-free or Ca2+-bound conditions. SDS-PAGE analysis of SEC fractions revealed that MICU2-NΔ84-CΔ28 exhibited the best purity among all the MICU2 truncations. The white vertical line refers to the fact that MW markers were loaded on the same SDS-PAGE, but not in the adjacent lanes.
