    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 400 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 P-1 (See i. Positive control of part IX.for a typical result). Dissolve the powder thoroughly by a gentle mix. Pipette 400 µL 1x Assay Diluent into each tube. Transfer 100 µL prepared P-1 into a tube with 400 µL 1x Asaay Diluent to produce a dilution series (shown below). Mix each tube thoroughly before the next transfer. 1x Assay Diluent serves as the background. Phospho-Stat5 ELISA 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 biotinylated antibody (Item C) before use. Add 100 µL of 1x Assay Diluent into the vial to prepare a biotinylated anti-phosphotyrosine 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 biotinylated phosphotyrosine antibody should be diluted with 1x Assay Diuent and used in step 4 of Part VII Assay Procedure.
      6. Briefly spin the HRP-Streptavidin concentrate vial (Item G) and pipette up and down to mix gently before use. HRP-Streptavidin concentrate should be diluted 600 fold with 1x Assay Diluent. For example: Briefly spin the vial (Item G) and pipette up and down to mix gently . Add 20 µL of HRP-Streptavidin concentrate into a tube with 12 mL 1x Assay Diluent to prepare a 600-fold diluted HRP-Streptavidin solution (don't store the diluted solution for next P-1 P-2 P-3 P-4 P-5 0 100 µL Positive Control 400 µL 1x Assay Diluent 100µl 100 µL 100 µL Phospho-Stat5 ELISA 7 day use). Mix well.
      7. Cell Lysate Buffer should be diluted 2-fold 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 lysis buffer. Solubilize cells at 4 x 107 cells/mL in 1x Lysis Buffer (we recommend adding protease and phosphatase inhibitors to lysis 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 100-fold dilution for your cell lysates with Assay Diluent (Item E) before use.
    Note: The fold dilution of sample used depends on the abundance of phosphorylated proteins and should be determined empiricallys. Phospho-Stat5 ELISA 5 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 biotinylated anti-phosphotyrosine antibody (Reagent Preparation step 5) to each well. Incubate for 1 hour at room temperature with shaking.
      5. Discard the solution. Repeat the wash as in step3. Phospho-Stat5 ELISA 8
      6. Add 100 µL of prepared 1X HRP-Streptavidin solution (see Reagent Preparation step 6) to each well. Incubate for 45 minutes at room temperature 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.
