Abstract: A determination method for determining reliability of a selective binding amount of a substance to be examined obtained as detection intensity of a label when a labeled substance to be examined binds to a selective binding substance fixed as a spot on a carrier includes: determining a position of the spot in image data obtained by imaging the detection intensity in the carrier and extracting a pixel group corresponding to the spot; calculating a ratio or a difference between a median value of the detection intensity of the pixel group extracted at the determining and a median value of the detection intensity of the pixel group excluding a certain top proportion of and/or a certain bottom proportion of pixels; and determining quality of the reliability based on the ratio or the difference calculated at the calculating and a certain reference value.

Abstract: Tough laminated composite material which comprise (A) long reinforcing fibers, (B) a matrix resin mixed with the long reinforcing fibers and (C1) a resin, preferably in the form of fine resin particles, forming a phase separate from said matrix resin which is localized in inter-layer zones, wherein 90% or more of said resin (C1) is localized in inter-layer zones and/or wherein the border length factor in the inter-layer zones is 2.5 or more and prepregs used to form the composite materials.
