应用

  • Cryocrystallography
  • 低温晶体学

特征

  • Synthetic CryoLoop on stainless steel MicroTube
  • MicroTube specially engineered with EasySnap notches
  • 不锈钢 MicroTube 上的合成 CryoLoop
    MicroTube 特别设计,带有 EasySnap 凹槽

描述

Mounted CryoLoops with 10 micron diameter nylon. The 10 micron Mounted CryoLoop shows less background diffraction than the 20 micron Mounted CryoLoop. Please note that the 10 micron Mounted CryoLoops are very flexible due to their small diameter. These nylon loops are bonded to hollow, stainless steel MicroTubes™ that are used to mount, freeze, and secure the crystal during cryocrystallographic procedures and X-ray data collection. The MicroTube is 24 mm in length and is specially engineered with EasySnap™ notches at the 10, 12, 14, 18, and 21 mm measures. To obtain the desired length of MicroTube, simply snap the MicroTube at the desired length and secure to the CrystalCap using epoxy or similar adhesive. These nylon loops show minimal diffraction, are thin for fast freezing, strong, and aerodynamic.

Most data collection geometries prefer or require a 22 mm length between the base of the cap and the beam. For a 22 mm overall length using the CrystalCap, CrystalCap ALS, CrystalCap ALS HT and CrystalCap SPINE HT, snap the MicroTube at the second notch from the bottom, creating an 18 mm MicroTube lenghth and secure to the CrystalCap using epoxy or similar adhesive. For a 22 mm over length using the CrystalCap Copper, CrystalCap Copper HT, CrystalCap ALS Copper HT snap the MicroTube at the fifth notch from the bottom (notch closest to the CryoLoop) and secure to the CrystalCap using epoxy or similar adhesive.

安装有 10 微米直径尼龙的 CryoLoops。 10 微米安装的 CryoLoop 显示的背景衍射比 20 微米安装的 CryoLoop 少。请注意,10 微米安装的 CryoLoop 因其小直径而非常灵活。这些尼龙环与中空不锈钢 MicroTubes™ 粘合,用于在低温晶体学程序和 X 射线数据收集过程中安装、冷冻和固定晶体。 MicroTube 的长度为 24 毫米,专门设计了 10、12、14、18 和 21 毫米尺寸的 EasySnap™ 凹槽。要获得所需长度的 MicroTube,只需将 MicroTube 卡入所需长度并使用环氧树脂或类似粘合剂固定到 CrystalCap。这些尼龙环显示出最小的衍射,很薄,可以快速冷冻,坚固且符合空气动力学。

大多数数据收集几何结构更喜欢或要求帽底和梁之间有 22 毫米的长度。对于使用 CrystalCap、CrystalCap ALS、CrystalCap ALS HT 和 CrystalCap SPINE HT 的 22 mm 总长度,将 MicroTube 从底部的第二个凹口处卡入,形成 18 mm 的 MicroTube 长度并使用环氧树脂或类似粘合剂固定到 CrystalCap。对于 22 mm 以上的长度,使用 CrystalCap Copper、CrystalCap Copper HT、CrystalCap ALS Copper HT 将 MicroTube 卡在从底部算起的第五个槽口(最靠近 CryoLoop 的槽口),并使用环氧树脂或类似粘合剂固定到 CrystalCap。

Dialysis Buttons

应用

  • Crystallization by dialysis, protein folding, & small volume sample dialysis
  • 通过透析、蛋白质折叠和小体积样品透析进行结晶

特征

  • Low volume dialysis
  • Fits in 24 well plates
  • Use over and over again
  • 低容量透析
    适合 24 孔板
    反复使用

描述

In the dialysis method, the sample in question is separated from the “precipitant” by a semi-permeable membrane which allows small reagent molecules to pass but prevents biological macromolecules from crossing the membrane.1-3

Dialysis Buttons are injection molded from polystyrene, and are the size of a small button. The sample is placed in this chamber so as to create a slight dome of liquid at the top of the button. A dialysis membrane is placed over the top of the button/sample and is held in place with an O-ring. The O-ring is held in place by a groove in the Dialysis Button. Dialysis Buttons are supplied with O-rings. The 5 µl to 100 µl sized dialysis buttons have an approximate overall height of 6 mm, an approximate outside diameter of 10 mm without an O-ring in place, and an approximate diameter of 12 mm with an O-ring in place. The 200 µl and 350 µl sized dialysis buttons have an approximate overall height of 8 mm, an approximate outside diameter of 15 mm without an O-ring in place, and an approximate diameter of 17 mm with an O-ring in place. Each package of dialysis buttons includes a plastic golf tee shaped applicator to assist with applying a dialysis membrane to the button and securing with the supplied o-ring.

在透析方法中,有问题的样品通过半透膜与“沉淀剂”分离,半透膜允许小试剂分子通过,但阻止生物大分子穿过膜。1-3

透析按钮由聚苯乙烯注塑成型,大小与小按钮相当。将样品放置在该腔室中,以便在按钮顶部形成一个轻微的液体圆顶。透析膜放置在按钮/样品的顶部,并用 O 形环固定到位。 O 形环由透析按钮中的凹槽固定到位。透析按钮配有 O 形圈。 5 µl 至 100 µl 大小的透析按钮的总高度约为 6 mm,外径约为 10 mm,未安装 O 形圈,直径约为 12 mm,安装了 O 形圈。 200 µl 和 350 µl 大小的透析按钮总高度约为 8 mm,外径约为 15 mm,不带 O 形圈,直径约为 17 mm,带 O 形圈。每个透析按钮包都包括一个塑料高尔夫球 T 形涂抹器,以帮助将透析膜应用到按钮上并使用随附的 O 形圈固定。

Micro-Bridges

应用

  • Sitting drop crystallization
  • Heavy atom soaks
  • Seeding
  • 坐滴结晶
    重原子浸泡
    播种

特征

  • Perform sitting drop experiments in 24 well hanging drop plates
  • Removable
  • 在 24 孔悬挂滴板中进行坐滴实验
    可拆卸的

描述

Micro-Bridges are small devices in the shape of a bridge that are designed to carry out sitting drop vapor diffusion crystallization when placed in a VDX™ Plate or Linbro® Plate. A single Micro-Bridge fits neatly into the reservoir of a standard 24 well VDX Plate for a sitting drop crystallization experiment. Once placed inside the wells, Micro-Bridges are stable and there is no need to stick them to the wells with grease or adhesive. It is therefore possible to transfer them to other wells during or after a crystallization experiment.

Why sitting drop? Placing the droplet in the indentation greatly reduces the risk of losing the protein by accident. Crystallization can be carried out in the presence of detergents and organic solvents which are compatible with polystyrene (such as MPD, iso-propanol, and ethanol). The protein drop is less affected by condensation problems. Soaking and seeding experiments can be carried out easily. Crystals can be transported more securely. Larger drop volumes can be used. Micro-Bridges have a concave indentation in the top surface of the bridge which holds the sample droplet during a crystallization experiment and prevents the droplet from spreading over a large area. Made from polystyrene, these parts are highly transparent and suitable for most crystallizations. The surface of the indentation is highly polished to facilitate the visual inspection of the drops under a microscope. The maximum drop volume for the Micro-Bridge is 35 µl. Reservoirs can be sealed with plain cover slides and vacuum grease or clear sealing tape.

Approximate dimensions: Height: 12 mm Length: 14 mm Width: 7 mm

微桥是桥形的小型设备,设计用于在放置在 VDX™ 板或 Linbro® 板中时进行坐滴蒸汽扩散结晶。单个 Micro-Bridge 可巧妙地装入标准 24 孔 VDX 板的储液器中,用于坐滴结晶实验。一旦放置在孔内,Micro-Bridges 就很稳定,无需用油脂或粘合剂将它们粘在孔上。因此,可以在结晶实验期间或之后将它们转移到其他孔中。

为什么要坐下来?将液滴放入压痕中可大大降低意外丢失蛋白质的风险。可以在与聚苯乙烯相容的去污剂和有机溶剂(如 MPD、异丙醇和乙醇)存在下进行结晶。蛋白质下降受冷凝问题的影响较小。可以轻松进行浸泡和播种实验。水晶可以更安全地运输。可以使用更大的液滴体积。微桥在桥的顶部表面有一个凹形压痕,用于在结晶实验期间固定样品液滴并防止液滴在大面积上扩散。这些部件由聚苯乙烯制成,高度透明,适用于大多数结晶。压痕表面经过高度抛光,便于在显微镜下目视检查液滴。 Micro-Bridge 的最大滴体积为 35 µl。可以使用普通盖玻片和真空润滑脂或透明密封胶带密封储液罐。

大概尺寸: 高度:12 毫米 长度:14 毫米 宽度:7 毫米

Solutions are stable at 2-8°C for months. Autoclaving is not recommended for any sulfonic acid buffer. When MES solutions are autoclaved, they turn yellow (although pH does not change measurably). The identity of the yellow breakdown product is unknown. When MES solutions are stored at room temperature, they can turn yellow within six months.
