商品介绍
Anti-Fade Mounting Medium (With DAPI) is a glycerol-based mounting medium containing an anti-fluorescence quenching reagent. It can be used to seal tissue or cell slides for fluorescence-related applications. After mounting, slides can be observed for several weeks without drying out or requiring sealing. This medium can help prolong fluorescence and maximise fluoresence intensity, and assist with antigen-antibody binding.

This medium is compatible with a wide range of fluorophores and fluorescent proteins, such as blue fluorescent protein, FITC, Cy2, Cy3, Cy5, Cy7, DAPI, rhodamine, Texas Red, AMCA, R6G, Hoechst 33258, AF, and more.

This medium contains DAPI, a blue fluorescent DNA stain which binds strongly to "A-T"-rich regions in DNA, exhibiting up to a 20-fold increase in fluorescence. It can pass through intact cell membranes, and therefore can be used to stain both live and fixed cells for fluorescence microscopy and flow cytometry. It can also be used for counting cells, measuring apoptosis, sorting cells based on DNA content, and as a nuclear segmentation tool in imaging analysis. DAPI has an absorption maxima at 340 nm and an emission maxima at 488 nm. When bound to double-stranded DNA, the absorption maxima changes to 358 nm (ultraviolet) and the emission maxima to 461 nm (blue).

Directions for use

Protocol

  1. Bring all reagents to room temperature before use.
  2. Use a pipette to remove excess liquid on the sample slide. Allow the slide to air dry slightly.
  3. Add 20 µl of Anti-Fade Mounting Medium on to the sample on the slide, or add an appropriate volume of Anti-Fade Mounting Medium in to the cell culture wells directly.
  4. Place a coverslip on the slide. Take care to avoid bubble formation.
  5. Observe under a fluorescence microscope. The coverslipped slide can be stored in the dark at 4 °C or at -20 °C for up to 3 weeks without fluorescence fading.

Notes:

  • Coverslips which contain Anti-Fade Mounting Medium must be stored in the dark.
  • This medium can help to slow down the rate of quenching, but does not eliminate it. It is therefore recommended to observe the slide and capture images as soon as possible.
  • Wear Personal Protective Equipment (PPE), such as lab coats, lab glasses and gloves, when using this product.

品牌介绍
Isotype Control 同型对照 同型对照(Isotype Control),使用与一抗相同种属来源、相同亚型、相同剂量和相同的免疫球蛋白及亚型的免疫球蛋白,用于消除由于抗体非特异性结合到细胞表面而产生的背景染色。 同型对照 同型对照的主要目的是确定一抗的结合是特异性的,而不是非特异性的Fc受体或与其他蛋白的相互作用。还可以用来竞争性的结合抗体,与功能阻断抗体发挥同样的功能。 同型对照要与一抗的来源,Ig分型和标记完全一致。 如果一抗是多抗,可以用an normal serum(与一抗相同的正常血清) (must be the same species as primary antibody)。This control is easy to achieve and can be used routinely in immunohistochemical staining.这个可以咨询试剂商。同型对照为免疫荧光标记中的阴性对照。由于荧光标记单抗的组来源不同,应选用相同来源的未标记单抗作为同型对照来 调整背景染色。举个例子:比如检测一抗为单抗的mouse anti rat CD11b,clone OX-42 purified IgG,那么它的isotype 是mouse IgG2a, 所以可以用purified(纯化的) mouse IgG2a来做OX-42的同型对照(Isotype Control)。一般的的生物技术公司和国内的代理都有出售。 同型对照:是指与MoAb相同的、未免疫小鼠的免疫球蛋白亚类,若使用直接免疫荧光染色法,同型对照也应标记荧光色素,如IgG1 FITC、IgG2a、PE等。主要考虑了细胞的自发荧光、FC受体介导的抗体结合和非特异性抗体结合等影响因素。此外,同型对照与MoAb所标记的荧光 色素、浓度、F:P比值(标记的荧光色素与免疫球蛋白分子的比值)应该相同为最佳,这对准确设定阴性与阳性细胞的界标有重要意义,切忌使用与MoAb不相 匹配的同型对照,最好为同一实验室、采用相同工艺或方法制备(如同一品牌)的产品。
