    Abstract: The invention relates to a method for determining homocysteine concentration in samples in which homocysteine is condensed using an enzyme cystathionine &bgr; sythase to form cystathionine. Pyruvate and/or ammonia are released from cystathionine by action of an enzyme, cystathionine &bgr; lyase, and homocysteine is regenerated. The release of pyruvate and/or ammonia can be correlated to the concentration of homocysteine present in the sample.

    Abstract translation: 本发明涉及一种测定样品中同型半胱氨酸浓度的方法,其中同型半胱氨酸使用胱硫醚β酶进行浓缩以形成胱硫醚。 丙酮酸和/或氨通过酶的作用从胱硫醚释放,胱硫醚β裂解酶和同型半胱氨酸被再生。 丙酮酸和/或氨的释放可以与样品中存在的同型半胱氨酸的浓度相关。
