1. Microtitration plate reader capable of absorbance measurement at 450 nm, 405nm and 630 nm.
2. Microplate orbital shaker.
3. Microplate washer.
4. Semi-automated/manual precision pipette to deliver 10-250 μL.
5. Vortex mixer.
6. Deionized water.

1. MBP Calibrator A-F and MBP Controls I & II: Tap and reconstitute MBP Calibrator A-F and MBP Controls I & II each with 1 mL deionized water. Mix well, and use immediately after reconstitution.
2. Wash Solution: Prepare Wash Solution by diluting Wash Concentrate A 25-fold with deionized water. The Wash Solution is stable for one (1) month at room temperature when stored in a tightly sealed bottle.
3. MBP Antibody-Biotin Conjugate Solution: The MBP Antibody- Biotin Conjugate Concentrate should be diluted at a ratio of 1 part conjugate to 50 parts of MBP Conjugate Diluent, according to the number of wells used. If an entire plate is to be used pipet exactly 220 μL of the Concentrate into 11 mL of the buffer.
4. Microtitration Wells: Select the number of coated wells required for the assay. The remaining unused wells should be placed in the re-sealable pouch with a desiccant. The pouch must be resealed to protect from moisture.

• Cerebrospinal fluid is the recommended sample type.
• Avoid assaying lipemic, hemolyzed or icteric samples.
• Each laboratory should determine the acceptability of its own CSF collection, shipping, and storage methods.
• Avoid repeated freezing and thawing of samples. Thaw samples no more than 3 times.

Allow all samples and reagents to reach room temperature. Mix reagents thoroughly by gentle inversion before use. Calibrators, controls and samples should be assayed in duplicate. NOTE: If the concentration of MBP in the sample is greater than the highest calibrator, dilute appropriately using MBP in spinal fluid with negligible MBP concentration or Calibrator A.

1. Mark the microtitration strips to be used.
2. Pipet 100 μL of the calibrators, controls and samples to the appropriate
3. Incubate the wells, shaking at 600-800 rpm on an orbital microplate shaker, for 1 hour at room temperature (23 ± 2 °C).
4. Prepare the Antibody-Biotin Conjugate Solution as described under the "Preparation of Reagents" section of this package insert.
5. Aspirate and wash each well 5 times with the wash solution (350 μL/per well) using an automatic microplate washer.
6. Add 100 μL of the Antibody-Biotin Conjugate Solution to each well using a repeater pipette.
7. Incubate the wells, shaking at 600-800 rpm on an orbital microplate shaker, for 1 hour at room temperature (23 ± 2 °C).
8. Aspirate and wash each well 5 times with the wash solution (350 μL/per well) using an automatic microplate washer.
9. Add 100 μL of the Streptavidin-Enzyme Conjugate-RTU to each well using a repeater pipette.
10. Incubate the plate, shaking at a fast speed (600-800 rpm) on an orbital microplate shaker, for 30 minutes at room temperature (23 ± 2 °C).
11. Aspirate and wash each strip 5 times with the Wash Solution (350 μL/per well) using an automatic microplate washer.
12. Add 100 μL of the TMB chromogen solution to each well using a repeater pipette. Avoid exposure to direct sunlight.
13. Incubate the wells, shaking at 600-800 rpm on an orbital microplate shaker, for 8-12 min at room temperature (23 ± 2 °C). NOTE: Visually monitor the color development to optimize the incubation time.
14. Add 100 μL of the stopping solution to each well using a repeater pipette. Read the absorbance of the solution in the wells within 20 minutes, using a microplate reader set to 450 nm. NOTE: Zero calibrator should be programmed as "Blank" while reading the optical density. If instrument has a wavelength correction, set the instrument to dual wavelength measurement at 450 nm with background wavelength correction at 630 nm.

NOTE: The results in this package insert were calculated by plotting the log optical density (OD) data on the y-axis and log MBP concentration on X-axis using a cubic regression curve-fit. Alternatively, log vs. log quadratic regression curve-fit can be used. Other data reduction methods may give slightly different results.

1. Optimum results can be obtained at incubation temperature of (23 ± 2 °C).
2. Calculate the mean optical density (OD) for each calibrator, Control, or Unknown.
3. Plot the log of the mean OD readings for each of the Calibrators along the y-axis versus log of the MBP concentrations in ng/mL along the x-axis, using a cubic regression curve-fit.
4. Determine the MBP concentrations of the Controls and Unknowns from the calibration curve by matching their mean OD readings with the corresponding MBP concentrations.
5. Any sample reading higher than the highest Calibrator should be appropriately diluted with the 0 ng/mL (Calibrator A) and re-assayed.
6. Any sample reading lower than the analytical sensitivity should be reported as such.
7. Multiply the value by a dilution factor, if required.
