    • There is disclosed a composition represented by the formula PIPn-L-S-Matrix, wherein PIPn is a phosphoinositide polyphosphate, L is a linker moiety, S is a scintillant, and Matrix is a solid support. Preferred linker moieties include succinimide and poly(ethylene glycol) linkers, and a preferred scintillant is 2-(4-amino-methylphenyl)-5-(4-biphenyl)-1,3,4-oxadiazole. In a preferred embodiment, the Matrix is a microtitre plate. The composition can be used for assaying phosphatidylinositol kinases and for screening compounds for inhibition of phosphatidylinositol kinase activity. Methods of making and using the compound are also disclosed.

    • Cross-linking of collagenous material may be achieved by treatment with compounds of the formula (I) Xm(R )(CHO)n, wherein R is an organic group having n+m functionality, X is a zwitterionic pendant group having an overall neutral charge, m is at least 1 and n is at least 2 (or a gem-diol, hemiacetal or acetal thereof). This results in the pendant amine groups of lysine residues present on the surface of the collagenous material to undergo a condensation reaction with the aldehyde groups present in formula (I) to form an imine linkage, thus fixing the biological moieties. The incorporation of the zwitterionic groups, suitably phosphoryl choline derivatives may have significant benefits in extending the life and reducing calcification of collagenous materials. One specific compound is 3-(oxyethyl-2'-(trimethylammoniumethyl)phosphate)-pentan-1,5-dial.
    • 胶原材料的交联可以通过用式(I)Xm(R 1)(CHO)n的化合物处理来实现,其中R 1是具有n + m官能团的有机基团,X是两性离子 具有总体中性电荷的侧基,m为至少1,n为至少2(或偕二醇,半缩醛或缩醛)。 这导致存在于胶原材料表面上的赖氨酸残基的侧胺基与式(I)中存在的醛基发生缩合反应,形成亚胺键,从而固定生物部分。 合适的磷酸胆碱衍生物的两性离子基团的并入在延长生命和减少胶原材料的钙化方面可能具有显着的益处。 一种具体的化合物是3-(氧乙基-2' - (三甲基铵乙基)磷酸酯) - 戊烷-1,5-表盘。
