Melanoma of the skin is considered as multiplex neoplastic system characterized by high tumor heterogeneity. MicroRNAs are a class of epigenetic regulators by which 90 % of human genome is controlled. At the present time more than 1 500 types of microRNAs is identified. Comparative analysis of micro...

Abstract. Present work describes a multiplex “sandvich” approach to enzyme-linked, solid-phase immunosorbent assay designed in microarray formate, aiming for quantitative evaluation of individual profile of cytokine expression. Its high specificity, throughput and sensitivity (30 to 20,000 pg/mL) ar...
