Zebrafish cathepsin D protein expression. A) Western blotting of CD in homogenates of un-fertilized eggs (UFE), embryos (at 30% epiboly, 1 dpf and 2 dpf) and larvae (at 3 dpf and 4 dpf). The filter was first probed with a polyclonal antibody against rat CD, stripped and re-probed with a monoclonal antibody against β-actin. The arrow points to the single-chain CD (41 kDa). Asterisks point to aspecific bands. The position of standard molecular weight proteins is indicated. One representative gel out of five independent experiment is shown. B) Colloidal Coomassie G-250 stained gel (after blotting) showing whole homogenate proteins of each sample loaded. C) Western blotting validation of the polyclonal anti-CD antibody against homogenates of 4 dpf larvae, PAC2 cells and SH-SY5Y cells (transfected with either the empty vector or the vector carrying the cDNA for human CD or for zebrafish CD). The position of the CD molecular forms recognized by the antibody is indicated on the right. The position of standard molecular weight is indicated on the left. Essentially a similar pattern of CD expression was obtained in two other independent experiments. |
