a proportion is then incorporated into and remains for an extended period within the intracisternal granules which are a feature of the rough endoplasmic reticulum within these cells in vitro most ( approximately 60 % ) of the labeled secretory product , however , is transferred to the golgi complex within 30 min and , within a further 10 min , becomes packaged into small ( approximately 200 mmicro ) electron-opaque secretory granules .
