Aufbereitung der Reagenzien:

1. Bring all reagents and samples to room temperature (18 - 25 °C) before use.
   2. Item E, Assay Diluent should be diluted 5-fold with deionized or distilled water before use.
   3. Preparation of Positive Control: Briefly spin the Positive Control vial of Item K. Add 500 µL 1x Assay Diluent (Item E, Assay Diluent should be diluted 5-fold with deionized or distilled water before use) into Item K vial to prepare a Positive Control (P-1) Solution (See i. Positive Control of part IX.for a typical result in page 9). Dissolve the powder thoroughly by a gentle mix (it can be removed by centrifuge if any precipitate in the solution is found). Pipette 270 µL 1x Assay Diluent into each tube. Use the Positive Control (1) to produce a dilution series (shown below). Mix each tube thoroughly before the next transfer. 1x Assay Diluent serves as the background. \ Phospho-Mek1 (Ser217/221) ELISA Kit Protocol 6
   4. If the Wash Concentrate (20x) (Item B) contains visible crystals, warm to room temperature and mix gently until dissolved. Dilute 20 mL of Wash Buffer Concentrate into deionized or distilled water to yield 400 mL of 1x Wash Buffer.
   5. Briefly spin the detection antibody (Item C) before use. Add Add 100 µL of 1x Assay Diluent into the vial to prepare a detection antibody concentrate. Pipette up and down to mix gently (the concentrate can be stored at 4 °C for 5 days or at - 80 °C for one month). The rabbit anti-Mek1 (Ser217/221) antibody should be diluted 55-fold with 1x Assay Diuent and used in step 4 of Part VII Assay Procedure.
   6. Briefly spin the HRP-conjugated anti-rabbit IgG (Item D) before use. Pipette up and down to mix gently. HRP-conjugated anti- rabbit IgG concentrate should be diluted 500-fold with 1x Assay Diuent. For example: Briefly spin the vial (ItemD) and pipette up and down to mix gently. Add 10 µL of HRP-conjugated anti- P-1 P-2 P-3 P-4 0 30 µL Positive Control powder 500 µL 1x Assay Diluent 30µl 270 µL \ Phospho-Mek1 (Ser217/221) ELISA Kit Protocol 7 rabbit IgG concentrate into a tube with 5 mL 1x Assay Diluent to prepare a 500-fold diluted HRP-conjugated anti-rabbit IgG solution.
   7. Cell Lysate Buffer should be diluted 2-folds with deionized or distilled water before use (recommend to add protease and phosphatase inhibitors). VII.

Aufbereitung der Proben:

Cell lysates - Rinse cells with PBS, making sure to remove any remaining PBS before adding the Cell Lysate Buffer. Solubilize cells at 4 x 107 cells/mL in 1x Cell Lysate Buffer (we recommend adding protease and phosphatase inhibitors to Cell Lysate Buffer prior to sample preparation). Pipette up and down to resuspend and incubate the lysates with shaking at 2 - 8° C for 30 minutes. Microcentrifuge at 13,000 rpm for 10 minutes at 2 - 8° C, and transfer the supernates into a clean test tube. Lysates should be used immediately or aliquoted and stored at -70 °C. Avoid repeated freeze-thaw cycles. Thawed lysates should be kept on ice prior to use.
For the initial experiment, we recommend to do a serial dilution testing such as 5-fold and 50-fold dilution for your cell lysates with 1x Assay Diluent (Item E) before use. \ Phospho-Mek1 (Ser217/221) ELISA Kit Protocol 5
Note: The fold dilution of sample used depends on the abundance of phosphorylated proteins and should be determined empirically. More of the sample can be used if signals are too weak. If signals are too strong, the sample can be diluted further.
Cell Lysate Buffer should be diluted 2-fold with deionized or distilled water before use (recommend to add protease and phosphatase inhibitors).

Testdurchführung:

1. Bring all reagents to room temperature (18 - 25 °C) before use. It is recommended that all samples or Positive Control should be run at least in duplicate.
   2. Add 100 µL of each sample or positive control into appropriate wells. Cover well with plate holder and incubate for 2.5 hours at room temperature or over night at 4 °C with shaking.
   3. Discard the solution and wash 4 times with 1x Wash Solution. Wash by filling each well with Wash Buffer (300 µL) using a multi-channel pipette or autowasher. Complete removal of liquid at each step is essential to good performance. After the last wash, remove any remaining Wash Buffer by aspirating or decanting. Invert the plate and blot it against clean paper towels.
   4. Add 100 µL of prepared 1x detection antibody anti-Mek1 (Ser217/221) (Reagent Preparation step 5) to each well. Incubate for 1 hour at room temperature with shaking. \ Phospho-Mek1 (Ser217/221) ELISA Kit Protocol 8
   5. Discard the solution. Repeat the wash as in step3.
   6. Add 100 µL of prepared 1x HRP-conjugated anti-rabbit IgG (see Reagent Preparation step 6) to each well. Incubate over night at 4oC with shaking.
   7. Discard the solution. Repeat the wash as in step3.
   8. Add 100 µL of TMB One-Step Substrate Reagent (Item H) to each well. Incubate for 30 minutes at room temperature in the dark with shaking.
   9. Add 50 µL of Stop Solution (Item I) to each well. Read at 450 nm immediately.
