Remove excess microplate strips from the plate 250l of stock frame, return them to the plastic pouch (P01) with the desiccant pack. 3. Add 100L per well of Dilution Buffer to Blank 4. Add 100 L of standard dilutions in reverse order of serial dilution, samples, or positive control per well. Cover with plate sealer. Incubate for 2 hours on microplate shaker at room temperature. 5. Aspirate each well and wash, repeating the process three times for a total of four washes. Wash by filling each well with 1x Wash Buffer (300L) using a squirt bottle, manifold dispenser, or autowasher. Complete removal of liquid at each step is essential for 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. 6.

ELISA PROTOCOL
Bring all reagents and samples to room
temperature before the start of the assay. Blank,
standard dilutions, positive control and samples
should be assayed in duplicate. ELISA Protocol may

need further optimization.

CALCULATION OF RESULTS
SPECIFICITY
Average the duplicate readings for each standard, PROTEIN NAME
positive control and sample, and subtract the Human CD36 ECD/Fc (Sf21 average zero standard optical density. Create a standard curve by reducing the data using computer Human CD36 ECD, His Tag software capable of generating a log-log curve fit. As Human CD320, ECD an alternative, construct a standard curve by plotting the mean absorbance for each standard on the y- axis against the concentration on the x-axis and draw a best fit curve through the points on the graph. The data may be linearized by plotting the log of the sCD36 concentrations versus the log of the O.D. and the best fit line can be determined by regression analysis. This procedure will produce an adequate but less precise fit of the data. LINEARITY
