Figure 4: This figure represents the Western blots of glutaminase within the DRG, brain, spinal cord, and kidney. A characteristic 65 kDa band was visualized in all the samples confirming the specificity of the antibody and the presence of the kidney/brain glutaminase isoform within the spinal cord and DRG. Western blots have been cropped to exclude the nonspecific IgG 53 kDa band and enhance the presentation of the 65 kDa band.
