| Abstract: | 125I]TID, a small photoreactive lipophylic reagent, was used to label intrinsic proteins of rabbit and rat sarcoplasmic reticulum membranes. A 160,000 glycoprotein, the Ca2+-ATPase and polypeptides of mol. wt 53-55,000, 30,000, 20,000 and 6000 dalton were labelled suggesting that these proteins are integral membrane components. |
