    Protocol
    1. Prepare all reagents, samples and standards as instructed in the manual.
    2. Add 100 μL of standard or sample to each well.
    3. Incubate 2.5 h at RT or O/N at 4 °C.
    4. Add 100 μL of prepared biotin antibody to each well.
    5. Incubate 1 h at RT.
    6. Add 100 μL of prepared Streptavidin solution to each well.
    7. Incubate 45 min at RT.
    8. Add 100 μL of TMB One-Step Substrate Reagent to each well.
    9. Incubate 30 min at RT.
    10. Add 50 μL of Stop Solution to each well.
    11. Read at 450 nm immediately.
    Reagent Preparation
    1. Bring all reagents and samples to room temperature (18 - 25 °C) before use.
      2. Sample dilution: Tissue lysate and cell lysate sample should be diluted at least 5-fold with 1x Sample Diluent Buffer.
      3. Sample Diluent Buffer (Item D) and Assay Diluent (Item E) should be diluted 5-fold with deionized or distilled water before use.
      4. Preparation of standard: Briefly spin the vial of Item C. Add 400 µL 1x Sample Diluent Buffer (Item D) into Item C vial to prepare a 25 ng/mL standard. Dissolve the powder thoroughly by a gentle mix. Add 40 µL VEGF standard from the vial of Item C, into a tube with 960.0 µL Sample Diluent Buffer to prepare a 1,000 pg/mL stock standard solution. Pipette 300 µL 1x Sample Diluent Buffer into each tube. Use the stock standard solution to produce a dilution series . Mix each tube thoroughly before the next transfer. 1x Sample Diluent Buffer serves as the zero standard (0 pg/mL). 200 µL 200 µL 200 µL 200myl 200 µL 200 µL 40 µL standard + 960 µL 1,000 400 160 64 25.6 10.2 4.1 0 pg/mL pg/mL pg/mL pg/mL pg/mL pg/mL pg/mL pg/mL
      5. 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.
      6. Briefly spin the Detection Antibody vial (Item F) before use. Add 100 µL of 1x Assay Diuent 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). The detection antibody concentrate should be diluted 80-fold with 1x Assay Diuent and used in step 4 of Part VI Assay Procedure.
      7. Briefly spin the HRP-Streptavidin concentrate vial (Item G) before use. HRP-Streptavidin Concentrate should be diluted 160-fold with 1x Assay Diuent. For example: Briefly spin the vial (Item G) and pipette up and down to mix gently . Add 100 µL of HRP-Streptavidin concentrate into a tube with 16 ml 1x Assay Diluent to prepare a 160-fold diluted HRP-Streptavidin solution (don't store the diluted solution for next day use). Mix well.
      8. Cell lysate buffer should be diluted 2-fold with deionized or distilled water (for cell lysate and tissue lysate).
    Assay Procedure
    1. Bring all reagents and samples to room temperature (18 - 25 °C) before use. It is recommended that all standards and samples be run at least in duplicate.
      2. Add 100 µL of each standard (see Reagent Preparation step 2) and sample into appropriate wells. Cover well and incubate for 2.5 hours at room temperature or over night at 4 °C with gentle shaking. We recommend using 50-500 myg/mL of total protein for lysate sample. The amount of sample used depends on the abundance of target protein. More of the sample can be used if signals are too weak. If signals are too strong, the sample can be diluted further.
      3. Discard the solution and wash 4 times with 1x Wash Solution. Wash by filling each well with Wash Buffer (300 myl) 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 1x prepared biotinylated antibody (Reagent Preparation step 6) to each well. Incubate for 1 hour at room temperature with gentle shaking.
      5. Discard the solution. Repeat the wash as in step
      6. Add 100 µL of prepared Streptavidin solution (see Reagent Preparation step 7) to each well. Incubate for 45 minutes at room temperature with gentle shaking.
      7. Discard the solution. Repeat the wash as in step
      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 gentle shaking.
      9. Add 50 µL of Stop Solution (Item I) to each well. Read at 450 nm immediately.
    Calculation of Results

    Calculate the mean absorbance for each set of duplicate standards, controls and samples, and subtract the average zero standard optical density. Plot the standard curve on log-log graph paper or using Sigma plot software, with standard concentration on the x-axis and absorbance on the y-axis. Draw the best-fit straight line through the standard points.
    Typical Data: These standard curves are for demonstration only. A standard curve must be run with each assay. Sample Diluent Buffer Mouse VEGF concentration (pg/mL) 1 10 100 1000 10000 O D =4 50 n m 0.1 1 10
    Sensitivity: The minimum detectable dose of VEGF is typically less than 2 pg/mL.
    Recovery: Recovery was determined by spiking various levels of mouse VEGF into mouse tissue lysate and cell lysate. Mean recoveries are as follows: Sample Type Average % Recovery Range ( %) Tissue lysate 87.87 81-102 Cell lysate 88.62 82-103
    Linearity: Sample Type Tissue Cell Lysate lysate 1:2 Average % of 92 93 Expected Range ( %) 82-102 83-103 1:4 Average % of 95 96 Expected Range ( %) 84-103 85-105
