Abstract: A microarray for predicting the prognosis of neuroblastoma, wherein the microarray has 25 to 45 probes related to good prognosis, which are hybridized to a gene transcript whose expression is increased in a good prognosis patient with neuroblastoma and are selected from 96 polynucleotides consisting of the nucleotide sequences of SEQ. ID NOs. 1, 5, 6, 14. 16, 17, 19, 22-24, 28, 29, 31, 37, 39, 40, 43, 44, 47-52, 54, 57-60, 62, 64, 65, 67, 68, 72-75, 77, 78, 80-82, 84, 87, 89-91, 94, 100, 103, 112, 113, 118, 120, 129, 130, 132, 136, 138, 142, 144, 145, 148, 150-153, 155, 158-160, 163-165, 169-171, 173, 174, 177, 178, 180-182, 184, 186, 187, 189, 191, 192, 194, 195, 198-200 or their partial continuous sequences or their complementary strands, and 25 to 45 probes related to poor prognosis, which are hybridized to a gene transcript whose expression is increased in a poor prognosis patient with neuroblastoma and are selected from 104 polynucleotides consisting of the nucleotide sequences of SEQ. ID NOs.

Abstract: In a method for producing a biochip comprising a large number of spots based on captures, the spots are arranged on a base plate 10 by supplying, onto the base plate 10, a plurality of types of the captures to be used to specifically react with a specimen in order to obtain information on a structure or a function of the specimen, an immobilization-reinforcing solution 16 is supplied onto the base plate 10 (first supply step). Subsequently, a sample 14, which is obtained in a sample preparation step, is supplied onto the immobilization-reinforcing solution 16 having been supplied onto the base plate 10 to produce the biochip thereby (second supply step).

Abstract: A probe solution composition containing a probe capable of binding specifically to a target substance and a moisturizer, which is utilized for spotting the probe to be fixed on a substrate, is provided. As a result, an increased detection sensitivity of a reaction chip, a higher spot shape stability and a simplified manufacturing process can be achieved.
