Abstract: An RNA capping method including a step of reacting a compound (1) represented by the following general formula (1) with an RNA in the presence of a Vaccinia virus capping enzyme (Rb1 represents an oxo group, an alkoxy group, or a halogen atom; Rb2 is either absent or represents an alkyl group; Rb3 represents an amino group or a hydrogen atom; Rb4 is either absent or represents a hydrogen atom or an alkyl group; Rr1 represents a hydroxy group, an alkoxy group having 1 to 3 carbon atoms, an amino group, an azide group, —OR1C?CH, or —R2R3; Rr2 represents a hydrogen atom, a hydroxy group, a halogen atom, an alkoxy group, an amino group, an azide group, —OR1C?CH, or —R2R3; and A1 represents an oxygen atom or a sulfur atom).

Abstract: In an electrical component socket, an electrical component can be removed easily even if a fixed contact potion bites into an electrical component terminal. In the electrical component socket (11), a floating plate (14) to accommodate an IC package (12) is provided in a socket body to be able to move up and down, and is biased upward by a biasing member. In a movable contact piece (15b) of a contact pin (15), a pressing projecting piece (15m) is formed. In the floating plate (14), a pressed part (14m) to be pressed by the pressing projecting piece (15m) is formed. When the movable contact piece (15b) is elastically deformed in an opening direction and a movable contact part (15g) separates from an IC lead (12b), the floating plate (14) rises upward by the biasing member, and the IC lead (12b) separates from a fixed contact part (15d).
