Western blots of the three MCT transporter proteins in granulocytes (G), lymphocytes (L), monocytes (M), and heart (H) as the positive control. Each of the blots is from a single gel, with extraneous lanes removed. The numbers at left show the location of globular protein standards relevant to the bands of interest. For the MCT1 blot, G₁ indicates that the granulocyte preparation is from a different blood sample than G, and the same distinction follows for L₁ and M₁ vs L and M in the MCT2 blot. Arrows point to the very weak granulocyte bands.
