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).
The Fructan test kit is suitable for the specific measurement and analysis of fructan in plant extracts and food products containing starch, sucrose and other sugars.
Colourimetric method for the determination of Fructan in plant
products, foodstuffs and other materials

Principle:
(sucrase)
(1) Sucrose + H2O → D-glucose + D-fructose
(β-amylase + maltase + pullulanase)
(2) Starch + maltosaccharides + H2O → D-glucose
(borohydride)
(3) D-Glucose + D-fructose → D-sorbitol + D-mannitol
(non-reducing)

(exo-inulinase + endo-inulinase)
(4) Fructan + H2O → D-glucose + D-fructose
(100°C, 6 min)
(5) D-Glucose + D-fructose + PAHBAH → PAHBAH colour complex
Kit size: 100 assays
Method: Spectrophotometric at 410 nm
Total assay time: ~ 90 min
