Diaion® HP20 is used as a filler in chromatography columns due to its extremely large pores. US $ 6-10 / Liter. To minimize the resin carbon blank, extensive cleaning (~1 week) was performed using a glass soxhlet extractor with a pyrex glass insert to hold the resin during washings of methanol, acetone, ethyl acetate and. DIAION HP-20 resin has many biological activities, for example, antioxidant, antitumorigenesis, and intestinal culture but also benzo(a)pyrene-induced tumorigenesis-glucosidase suppressing activities. Application Diaion ® HP-20 is an adsorbent resin used for the capture of hydrophobic compounds. 40 on experimental lung metastasis and the invasion of B16-BL6 melanoma cells. The present invention relates to a fermentation and purification method of tricyclo compounds, especially FK506 and/or FK520, in detail, relates to a purification method by adding a hydrophobic adsorbent resin as their carrier in a culturing step of FK506 and/or FK520 FK506 producing bacteria. It offers nice balance of pressure flow. Diaion|r HP20 is used as a filler in chromatography columns due to its extremely large pores. casein media in the presence of the Diaion HP-20 resin (50 g/L medium). Extraction of secondary metabolites using Diaion HP-20 The extraction of secondary metabolites was done by using Diaion HP-20 poly aromatic adsorbent resin from culture supernatant. Diaion HP-20 was used for removal of chlorophyll from the fractions by increasing the gradient of methanol in water. The initial n‐butanol extract was subjected to chromatography on a Diaion HP‐20 column, yielding 80 and 100% methanol eluates with AK‐releasing activity. Theory of Ion. Subsequently, sensory-guided fractionation will be conducted using a combination of chromatographic techniques, inclusive of passage over reversed-phase macroresins, such as Diaion HP-20, as well as Sephadex gels and silica gel-based sorbents, until pure sweettasting molecules are obtained. Plant material The Stem and rhizome of S. activated carbon, green tea leaves, microcrystalline naphthalene, cellulose, and Diaion HP-20. by ultrasonic. The production method of claim 1, wherein the step of treating the extract with the synthetic resin adsorbent comprises, bringing the extract and the synthetic resin adsorbent into contact with each other, eluting the adsorbed material from the adsorbent with an aqueous solution containing alcohol in a ratio of 10 to 30 volume %, and recovering. 이온교환수지 목록표 Ion Exchange Resin Product List 경기도 성남시 분당구 구미동18 시그마2빌딩 D-303 Tel. ppt,大孔吸附树脂 Macroporous Resin ——MCI 主要内容 大孔树脂内容简介 MCI系列大孔树脂介绍 HP系列(HP-20)大孔树脂介绍 各类型树脂的用途 参考文献 第一部分 大孔树脂内容简介: 1. Inclusion of Diaion HP-20 resin resulted in the selective production of unreduced azaphilone congeners, in addition to the early intermediate FK17-P2a, from ∆ and ∆ strains that would otherwise mainly produce reduced congeners. Non-saponin fraction, which was adsorbed on Diaion HP-20 resin, was removed by eluating with H₂O and 25% spirit. After 28-day fermentation, the aqueous solution was filtered and HP20 resin was extracted with methanol (3 × 500 mL). 44%, respectively. This operation was repeated with 6 liters of 10% formic acid. Monomer-Polymer and Dajac Labs. I already packed and conditioned the Diaion HP 20 resin column with water. 00 as basic sum plus value added tax. Products Product Name; Ion Exchange Resins: Strongly Acidic Cation Exchange Resins (Gel, Porous, Highly Porous Type and Industrial Chromatography) DIAION™ SK, UBK, PK series. The nbuthanol extract isolate using column chromatography method with stationer phase is resin diaion hp 20 and eluent ethanol: water in various concentration, isolation result is got 5 fraction. by ultrasonic. *Please select more than one item to compare. Abstract: Diaion HP-20 was used for on-line separation/pre-concentration and determination of lead by flow injection flame atomic absorption spectrometry.

Their structures were identified on the basis of physicochemical and spectroscopic analysis. 9 nm analytical lines [20,21]. 2016) and used as crude metabolite formulations (CM F). Structural determination of two novel unreduced azaphilones from the ∆ strain was accomplished. Proposed process for lactic acid recovery and purification 110 Figure 4. 欢迎前来中国供应商(www. It is also useful for the purification of peptides, proteins, fermentation products, polyphenols and cephalosporin C. Louis, MO, USA) and Sephadex. dryness and resin chromatography afforded 4 fractions (F1–F4). The same amount of sterile water and resin were also added to the root cultures for the negative control. HP-20 proved more effective at accumulating the toxins, with a higher percentage of positive samples and a higher ratio of toxin adsorbed relative to XAD761.
