Endoplasmic Reticulum Isolation Kit

The endoplasmic reticulum (ER) is a network of interconnected tubules, vesicles, and sacs. It plays a role in specialized cellular functions including protein synthesis, sequestering of calcium, production of steroids, storage and production of glycogen, and insertion of membrane proteins.

The Endoplasmic Reticulum Isolation Kit contains all the reagents required for ER preparations with various degrees of purity: crude ER (microsomes), Ca²⁺ precipitated rough ER (RER) enriched microsomes, and density gradient purified rough ER (RER) and smooth ER (SER). The ER isolation process can be monitored by measuring the activity of NADPH cytochrome c reductase using the Cytochrome c Reductase Assay Kit, (Cat. No. CY0100). The enzyme is an ER membrane protein that is commonly used as an ER marker. The isolated ER can be used for studying the cytochrome P450 system and xenobiotic metabolism, for studying lipid metabolism, and for the recovery of ER membrane and lumenal proteins. The kit was tested with rat liver, kidney, and brain; mouse liver; rabbit liver, kidney, spleen, heart, and brain; and with Jurkat and HeLa cell lines.

The Endoplasmic Reticulum Isolation Kit is used for the efficient enrichment of functional endoplasmic reticulum (ER) from mammalian tissue or cell culture. The isolated ER are useful for protein synthesis, degradation and metabolic pathway analysis. Metabolic abnormalities of ER include carnitine acetyltransferase deficiency in children, cystic fibrosis and many more ER protein retention disorders. Suitable for up to 50 g of tissue or ~20 mL of packed tissue.
