Abstract: In the case of assaying the level of complex AB in a sample which likely contains the complex AB composed of substance A with another substance B, the complex is assayed by the competitive homogeneous assay method with the use of reagents including a reagent containing partner C specifically binding to substance A, a reagent containing partner D specifically binding to substance B, a reagent containing fine particles carrying substance A or an analog thereof and substance B or an analog thereof, and a reagent containing partner C specifically binding to substance A and partner D specifically binding to substance B. Thus, the complex in the sample can be easily assayed. The above method is applicable to general-purpose biochemical automatic analyzers.

Abstract: The present invention provides a transglycosylation method and a protein catalyzing a transglycosylation reaction. A reaction of transferring a galactosyl?1?3N-acetylgalactosaminyl group from a sugar donor containing a sugar chain having a galactosyl?1?3N-acetylgalactosaminyl group bound thereto at the ?-position, to a sugar chain acceptor, is carried out in the presence of a protein having an endo-?-N-acetylgalactosaminidase activity and a transglycosylation activity.

Abstract: A light-weight super high vacuum vessel is disclosed in which a super high vacuum pressure over 10.sup.-10 Torr or over 10.sup.-11 Torr can be achieved using a simple evacuation system and/or with a sealing structure. The super high vacuum vessel contains a member comprising: from 0.02 wt. % to 1.00 wt. % of at least one platinum-group metal selected from the group consisting of Pd, Pt, Rh, Ru, Re, and Os; from 0.1 wt. % to 3.0 wt. % of at least one transition metal selected from the group consisting of Co, Fe, Cr, Ni, Mn, and Cu; from 0.1 wt. % to 3.0 wt. % of at least one rare earth series element selected from the group consisting of La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, and Y; impurity elements of C, N, and O, C being equal to or less than 0.05 wt. %, N being equal to or less than 0.05 wt. %, O being equal to or less than 0.08 wt. %; and Ti and inevitable impurities.
