  • 食物纤维测定试剂盒

    2008-07-23 09:00:20

    上海西宝生物 (13817370083)提供食物纤维测定试剂盒
           本产品为基于简化Prosky法的酶试剂盒。使用本产品时无需进行酶处理时的pH调整,可以同时进行蛋白酶及淀粉葡萄糖苷酶处理。与现有的Prosky法试剂盒相比,本产品操作更加简单,同时测量精度也更高。

    特点:
    操作简单。            进行酶处理时不需要调整pH。

    测量精度高。          酶处理时间缩短。

    操作方法:

    1.    将试验材料溶解于MES/Tris缓冲液中

    2.    热稳定α-淀粉酶处理 (pH6.3 在95℃放置30分钟)

    3.    蛋白酶、淀粉葡萄糖苷酶处理 (pH6.3 在60℃放置30分钟)

    4.    加入4倍95%乙醇(约200ml)

    5.    放置1小时,过滤

    6.    乙醇、丙酮清洗

    7.    干燥(一夜)

    8.    蛋白质定量(凯氏法)及灰份定量

    9.    总食物纤维

    优势:
    1.    无需再次调整pH浓度,酶处理时间缩短。
    2.    乙醇使用量减少。

    A product form. in which the optical isomer alkannin has been removed. Shikonin is contained in the root of perennial murasaki (Lith-ospermum erythrorhizon Sieb.'et Zucc.) growing naturally in Japan, China and Korean peninsula.
    A red-purple dye extracted from the root of murasaki is being used as cosmetic ingredients. Antiinflammatory effect, wound healing acceleration, antitumor effect, etc. have been reported as the pharmacological effects of the active component of shikonin. In shikonin, alkannin is present as an optical isomer.
    Shikonin standard and alkannin standard that have now been commercialized are both listed in the Japanese Pharmacopoeia, 14th Edition, and are used for identification and ingredient content determination of the active component shikonin.

    2008-06-04 09:39:51

    1、食物纤维测定试剂盒
    本产品为基于简化Prosky法的酶试剂盒。使用本产品时无需进行酶处理时的pH调整,可以同时进行蛋白酶及淀粉葡萄糖苷酶处理。与现有的Prosky法试剂盒相比,本产品操作更加简单,同时测量精度也更高。

    特点:
    ● 操作简单。               ● 进行酶处理时不需要调整pH。
    ● 测量精度高。         ● 酶处理时间缩短。

    操作方法:
    1.    将试验材料溶解于MES/Tris缓冲液中
    2.    热稳定α-淀粉酶处理 (pH6.3 在95℃放置30分钟)
    3.    蛋白酶、淀粉葡萄糖苷酶处理 (pH6.3 在60℃放置30分钟)
    4.    加入4倍95%乙醇(约200ml)
    5.    放置1小时,过滤
    6.    乙醇、丙酮清洗
    7.    干燥(一夜)
    8.    蛋白质定量(凯氏法)及灰份定量
    9.    总食物纤维
    优势:
    1.    无需再次调整pH浓度,酶处理时间缩短。
    2.    乙醇使用量减少。

    Green Chemiluminescent CD      1mg   
    A new luminescent reagent developed by Assistant Professor Katsunori Teranishi of the Mie University. It has both the molecule reacting to superoxide and the molecule receiving resultant energy and producing luminescence in one cyclodextrin molecule, and is useful in analysing superoxide anions. It has a luminescence wavelength in the long-wavelength range (530 nm), is hardly affected by other biological components during measurement, and has a sensitivity about 20 times higher than the conventional reagent that produces chemiluminescence in the long-wavelength range.
    This product is for research use only.  Do not administer it to human.

    Green Chemiluminescent probe for superoxide anions
    Green Chemiluminescent CD is a highly sensitive chemiluminescence probe, which was developed by Dr. Teranishi of Mie University, Japan.  This probe reacts with superoxide anion and produces luminescence at long wavelengths.  Therefore the luminescence remains nearly unaffected by biomaterials.  Additionally, this probe is more sensitive than other probes which produce luminescence at long wavelengths.

    Features

       1. High luminescence intensity

       2. Luminescence at long wavelengths (530 nm)


    Solubility
    Soluble to hot methanol : H2O (1:1) containing 0.1% TFA.

    3--4-二氯甲基-5-羟基-2(5)-呋喃酮(3-chloro-4-(dichloromethyl)-5-hydroxy-2[5H] -furanoneMX),是饮用水氯化消毒副产物之一,由氯与水源水中的有机腐殖酸作用生成。人体接触MX的途径主要为通过饮食和饮水摄入以及经过皮肤吸收。MX在氯化自来水的含量仅为267 ng/L[1],但是众多的体内体外实验均显示了MX的遗传毒性和致癌性,国际癌症研究署(IARC)已将MX列为人类可能致癌物。MX可致鼠伤寒沙门氏菌TA100 60%~87%的检测菌落发生GCTA置换[24];致大肠杆菌ATCG突变[5];致中国仓鼠卵巢细胞HPRT基因GCTA突变、ATTA颠换、GC碱基对缺失、大片段缺失和插入[6]。因此,MX导致的基因改变可能是其遗传毒性机制的一个重要方面。
