Immunoblot detects β5 integrin expression after PN7, whereas αv and β3 are expressed at constant adult levels from birth. In RPE obtained from rats of various ages, β5 integrin was first detected at PN7 but acquired its adult expression level only at PN11 (A1, 10 μg protein per lane, A2, 50 μg per lane). β3 and αv integrins were expressed at adult levels from PN2 (B and C, 50 μg per lane). RPE-J (J) and ARPE-19 (A19) cell lines displayed similar integrin expression levels as adult RPE (A2, B, C, 50 μg per lane). Molecular mass standards are indicated in kDa.
