Figure 7. Rax protein in the adult rat pineal gland and retina.
(a) Elimination of a 37 kDa immunopositive band by pre-absorption with Rax peptide, indicating that the detected band represents Rax protein (NP_446130.1; predicted molecular weight = 36.3 kDa). (b) A 37 kDa band is detected specifically in the extracts of the pineal gland and retina, but not in other tissues examined. Tissues were collected from rats euthanized at ZT12. Arrows indicate the position of the Rax band and molecular weight markers.
