To investigate the ability of ADA isozyme expression to discriminatebetweem lymphoid and nonlymphoid cell types in acute leukemia,the gelfiltration with FPLC system was used as micromethod for ADA isozymeanalysis.

为进一步阐明白血病细胞ADA同工酶生化性质，探讨制备ADA同工酶抗体的可能性，我们采用分子筛FPLC和阴离子交换FPLC系统二步法分离纯化健康人血清、单个核细胞和急性粒单核细胞白血病细胞ADA同工酶，获得部分纯化ADA1和ADA2，ADA1纯化71.62倍，活力62.2u/mg pr，ADA2纯化37倍，活力42.8u/mg pr，ADA总回收率44%，2步FPLC层析法酶活力回收率分别为68.4%和81.5%。

In this deposit, ore bodies exist in the stratoid form and are c ontrolled by thrust faults. The host rocks are limestone in Bolila Formation of Late Triassic Jiezha Group and in Gadikao Formation of Early-Middle Permian Kaix i nling Group, with strong dolomitization and weak silicification. Minerals are ra ther simple and consist of sphalerite, galena, pyrite, calcite, dolomite and barite. The important ore textures are colloforms such as framboid and crust and xenom orphic grains, and the ore structures are in disseminated, brecciated, veinlike and lumpy forms.

东莫扎抓铅锌矿床矿体呈似层状展布，产状严格受到矿区逆冲断层的控制，赋矿围岩为上三叠统结扎群波里拉组灰岩和下-中二叠统开心岭群尕迪考组灰岩，发育强白云石化和弱硅化，矿物组合简单，主要为闪锌矿+方铅矿+黄铁矿+白云石+方解石+重晶石，矿石结构以皮壳状、草莓状等胶状结构和他形粒状结构为主，矿石构造为浸染状、角砾状、团块状和脉状。
