Abstract Amino acid sequence and the location of seven galactosamine oligosaccharide moieties of the hinge region of the δ chain of human IgD NIG-65 have been determined. These oligosaccharide moieties are distributed in two distinct fashions: 1) three clusters each consisting of five amino acid residues with two consecutive attachment sites either Ala-X-Ala-Ser-Ser or Ala-X-Ala-Thr-Thr, where X can be any amino acid including proline, 2) one triplet sequence Val-Pro-Thr with one attachment site. We propose two rules with regard to the acceptor sequence for galactosamine oligosaccharides, the quintet sequence rule and triplet sequence rule.

70名のヒト精漿について変性剤を加えないミクロ二次元電気泳動を行った. 精漿蛋白の泳動像についてみるとMW5,000から1,000,000およびpI3.5からpI8の広範囲にわたり, 約80個のスポットが認められた. 精漿中のAlbおよびAlbより高分子領域の蛋白質については, ほとんどが血清にくらべてその含有量が少なかった.精漿蛋白の低分子領域 (MW5,000付近) では, 5~6個のスポットしか検出されない個体と10数個のスポットが検出される個体との2群がみられたが, このことは健康および不妊歴との相関は認められなかった. また, 精漿の低分子領域 (MW20,000付近) で精漿特異蛋白とされるγ-Seminoprotein が5本の線状のスポットとして検出された.
