果聚糖检测试剂盒 Fructan Assay Kit

果聚糖检测试剂盒 Fructan Assay Kit
商品说明:

产品名称:果聚糖检测试剂盒
英文名称:Fructan Assay Kit
型号规格:100次
品牌:爱尔兰Megazyme公司

果聚糖广泛分布于植物界。单子叶植物,双子叶植物和绿藻中均存在。

以分子结构和分子重量区别果聚糖。也可以分为三类:菊粉组,果聚糖组和带支链组。菊粉组主要或专门由果糖基果糖键组成。果聚糖组主要或专门由果糖基果糖键组成。带支链组由大量的(2→1)和(2→6)果糖基果糖键共同组成。

目前存在很多测定植物材料和食品中果聚糖的方法。被广泛接受的是水解为D-果糖(和D-葡萄糖)后再测定的方法。这存在将蔗糖,D-果糖和D-葡萄糖分别去除或测定的问题,Pontis(1966)已经报道了蔗糖,D-葡萄糖和D-果糖的去除方法,利用蔗糖酶水解蔗糖,再通过氢氧化钠煮沸破坏随之产生的D-果糖和D-葡萄糖及原有的单糖。据报道,蔗糖酶对菊粉组低聚果糖的作用是缓慢的,可以通过选择正确的孵育时间使其失效。通过测定目前使用的纯化的酵母蔗糖酶,发现很难。
但是,本试剂盒提供的方法操作简单,使用标准实验室设备,并且是精确性,可重复性和专一性都很好。采用的酶是高纯度酶,专一性水解蔗糖,淀粉和果聚糖。采用的蔗糖酶快速水解蔗糖但对1-蔗果三糖和其他果聚糖的水解活性可以忽略不计(McCleary和Blakeney,1999)(图2)。在底物浓度为10 mg/mL时,蔗糖与1-蔗果三糖的相对水解比率为3,800:1。
原理:

蔗糖被蔗糖酶水解为D-葡萄糖和D-果糖。同时,如果样品中存在淀粉和麦芽多糖通过高纯β-淀粉酶,普鲁兰酶和麦芽糖酶联合作用被水解D-葡萄糖。用碱性***物处理生成的还原糖,将其继续被还原为糖醇。用稀释的乙酸将溶液调至中性,并去除过量的***物。果聚糖被纯化果聚糖酶(菊粉外切酶)水解为D-葡萄糖和D-果糖,通过PAHBAH法测定生成的还原糖。这个方法方便操作,D-葡萄糖和D-果糖的对应颜色一致。含有半乳糖苷蔗糖寡糖的样品如(棉子糖)在蔗糖/淀粉酶混合物(酶溶液1)处理前推荐使用α-半乳糖苷酶(来源于黑曲霉)孵育。释放的单糖通过碱性***物处理去除。如果处理中包括这一步骤,需要在计算中考虑体积的变化(如溶液5的最终体积应用1.15mL代替1.1mL).

α-淀粉酶/液化酶/淀粉糖化酶检测试剂盒

α-淀粉酶/液化酶/淀粉糖化酶检测试剂盒

产品货号:K-CERA
产品品名:α-淀粉酶检测试剂盒
英文品名:Ceralpha: α-Amylase Assay Kit
规格型号:100 assays per kit
α-淀粉酶能水解淀粉中的α-1,4-葡萄糖苷键。能将淀粉切断成长短不一的短链糊精和少量的低分子糖类,从而使淀粉糊的黏度迅速下降,即起到降低稠度和“液化”的作用,所以此类淀粉酶又称为液化酶。
