General description

Total protein extraction kit is an excellent tool for the initial purification and preparation of proteins from any tissues and cells. Total protein isolated by this kit is native and can be used for downstream applications including SDS-PAGE, Western blotting, gel mobility shift, protein assays and other procedures. The kit is easy to use: no scraping, no freeze-thaw cycles, and no sonication.

This kit contains enough reagents for the isolation of protein from 5 grams of tissue or cultured cells.

Application

Isolate protein from large samples <br /><br />
Isolate protein either from tissues or from cultured cells <br /><br />· Protein is intact, and some proteins purified by this kit could be over 200 kd in mass <br /><br />The isolated protein can be used for Western Blot, DNA-protein interaction, enzymatic activity analysis, protein-protein interaction, and immunoprecipitation and tissue specific expression identification. <br /><br />PROTOCOL: <br /><br />Important: <br /><br />Aliquot 50X PI on ice and store at -20°C. <br /><br />Always make fresh working solutions before the isolation of proteins. <br /><br />1. Dilute 50X PI solution to 1X PI in TM buffer keeping the solution on ice. <br /><br />2. Weigh certain tissues and chop them into small pieces. <br /><br />3. Keep the tissues on dry ice. <br /><br />4. Add 1X PI to the tissue at 2.5 mL per gram of tissue or per 25 million cells, and put in ice for 5 minutes. <br /><br />5. Homogenize the tissue or cells for 20 seconds and then put on dry ice for 15 seconds. <br /><br />6. Homogenize the tissue or cells for the second 20 seconds. (A third 20 seconds homogenization may be required if the tissue or cells are not well homogenized.) <br /><br />7. Rotate the homogenized tissue or cells at 4°C for 20 minutes. <br /><br />8. Centrifuge at 11,000 rpm at 4°C for 20 minutes. <br /><br />9. Collect the supernatant. <br /><br />10. Determine the concentration of the total protein.
