Basic procedure for immunoprecipitation assay using IP-Readyª products. These are basic guidelines and may need to be modified for your particular application:_x000B__x000B_Prep of PBSTDS: Mix 100 ml of 10x PBS with 10 ml of 100% Triton X-100; 5 g of sodium deoxycholate and 1.0 g sodium dodecyl sulfate. Include a cocktail of protease inhibitors, such as 1 mM EDTA; 1 µg/ml Pepstatin and 0.2 mM PMSF from 100 mM stock in 2-propanol, or a cocktail of you choosing; Dilute this solution to 1 L with distilled water._x000B__x000B_1. Preclear lysate or media by adding ~1 µg of normal IgG from the same species from which the primary antibody is derived to remove nonspecific proteins._x000B_2. Incubate for 1 hour at 4¼C and then centrifuge at 1,500 rpm reserving supernatant for specific IP._x000B_3. Determine total protein of the sample._x000B_4. To a 1.5 ml Eppendorf tube, add the following: Cell lysate (1 mg total protein), 1 µg of purified primary antibody and 10 µl of packed beads._x000B_5. Cap tubes and incubate at 4¼C on rocker platform or rotating device for 2 to 24 hours._x000B_6. Centrifuge at 2,500 rpm for 15 minutes at 4oC and collect immunoprecipitate._x000B_7. Wash pellet 4 times with 1.0 ml of PBSTDS, repeating centrifuge step above (step 6) each time._x000B_8. After final wash, aspirate and discard supernatant and resuspend pellet in 40-50 µl of electrophoresis sample buffer._x000B_9. Analyze samples by either SDS-PAGE or transfer to a membrane and detect by Western blot.
The purest agarose was used in the production of Protein G Agarose IP- antibody Antibody Purification Reagent by nordc.If you buy Antibodies supplied by nordc they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.
Antibodies are affinity purified with an antigen coated column or protein A or G agarose or beads. DNA is purified with endotoxin free silica columns or anion exchange resins. nordc supplies purification kits and ultra pure reagents.
