• Pre-coated 96-Well Microplate
• Standard
• Standard Diluent Buffer
• Wash Buffer
• Detection Reagent A
• Detection Reagent B
• Diluent A
• Diluent B
• TMB Substrate
• Stop Solution
• Plate Sealer

• 37°C incubator
• Multi and single channel pipettes and sterile pipette tips
• Squirt bottle or automated microplate washer
• 1.5 ml tubes
• Distilled water
• Absorbent filter papers
• 100 ml and 1 liter graduated cylinders
• Microplate reader (wavelength: 450 nm)
• ELISA Shaker

• Serum: Samples should be collected into a serum separator tube. Coagulate the serum by leaving the tube undisturbed in a vertical position overnight at 4°C or at room temperature for up to 60 minutes. Centrifuge at approximately 1000 × g for 20 min. Analyze the serum immediately or aliquot and store at -20°C or -80°C.

• Plasma: Collect plasma using heparin or EDTA as an anticoagulant. Centrifuge for 15 minutes at 1000 × g within 30 minutes of collection. Assay immediately or aliquot and store at -20°C or -80°C. Avoid hemolysis and high cholesterol samples.

• Tissue homogenates: The preparation of tissue homogenates will vary depending upon tissue type – this is just an example. Rinse tissues with ice-cold PBS to remove the excess of blood. Weigh before homogenization. Finely mince tissues and homogenize with a tissue homogenizer on ice in PBS and sonicate the cell suspension. Centrifuge the homogenates at 5000 × g for 5 min and collect the supernatant. Assay immediately or aliquot and store at -20°C.

This procedure is provided for reference only. The product manual may differ slightly. The product should be used as stated on the product manual included and delivered together with the product.

• 1) Standard: Prepare the standard with the recommended volume of Standard Diluent Buffer, to make the standard solution. Then use the Standard Diluent buffer to carry out serial dilutions of the standard solution, as instructed in the Protocol.

• 2) Wash Buffer: Dilute the concentrated Wash Buffer with distilled water, as instructed in the Protocol.

• 3) Detection Reagent Preparation: Calculate the total volume of working solution required. Dilute Detection Reagent A and Detection Reagent B with Diluent A and Diluent B, respectively, at 1:100.

• 1) Set standard, test samples and control wells.

• 2) Aliquot 50 µl of diluted standard into the standard wells.

• 3) Aliquot 50 µl of Standard Diluent buffer into the control (zero) well.

• 4) Aliquot 50 µl of diluted samples into the sample wells.

• 5) Immediately aliquot 50 µl of Detection Reagent A to each well. Incubate for 45 mins at 37 °C.

• 6) Wash 3 times.

• 7) Aliquot 100 µl of Detection Reagent B to each well. Incubate for 30 mins at 37 °C.

• 8) Wash 5 times.

• 9) Aliquot 90 µl of TMB Substrate to each well. Incubate for 10-20 mins at 37 °C.

• 10) Aliquot 50 µl of Stop Solution.

• 11) Measure the OD at 450 nm.

Intra-assay Precision (Precision within an assay): 3 samples with low, medium and high levels of D-Dimer were tested 20 times on one plate, respectively.

Inter-assay Precision (Precision between assays): 3 samples with low, medium and high levels of D-Dimer were tested on 3 different plates, 8 replicates in each plate.

CV (%) = (Standard Deviation / mean) × 100

Intra-Assay: CV<10%
