Special reagent storage conditions are specified on each product page. Unless otherwise specified, the following conditions are recommended for all Lumiprobe products:

• Store at -20 Centigrade in the dark
• Transportation at room temperature for 2-3 weeks is acceptable
• Keep away from direct sunlight, and avoid long-term exposure to ambient light

The dyes are most stable at -20 Centigrade, but they can be shipped at room temperature without any deterioration for 2-3 weeks. Therefore, there is no need to ship them on ice.

Many products, such as dyes, exhibit some photosensitivity. However, unless otherwise specified on product page, sensitivity to the light is very modest, and there is no need to use dark packaging, or work in the dark. However, direct sun exposure should be avoided (because sunlight contains significant portion of UV light, which is more harmful to fluorophores). And ambient light exposure should be limited – do not let dyes remain in the ambient light for days or weeks.

Some of the products, such as NHS esters, are hydrolyzed by water which is present in the atmosphere, especially in humid environment. When the reagent is taken from the refrigerator, it is necessary to heat the vial to room temperature before opening. Otherwise, atmospheric humidity will immediately condense on cold walls inside the vial, and remain there after closing, decreasing reagent shelf life. After using the reagent, purge the vial with inert gas (dry nitrogen or argon) when possible before closing the vial – this will extend reagent shelf life more. Be careful with gas flow rate when purging powders such as cyanine dye NHS esters, because strong gas jet can bring airborne powder out of the vial.

Adhere to this simple rules to keep your reagents in good shape. And please feel free to contact our technical support about shipping conditions.

每个产品页上都规定了特殊的试剂储存条件。除另有指明外,建议所有发光探测器产品具备下列条件:

• 在黑暗中储存在-20摄氏度
• 允许在室温下运输2-3周。
• 远离阳光直射,避免长期接触环境光

染料在-20摄氏度时最稳定,但它们可以在室温下运输,在2-3周内不会变质。因此,没有必要在冰上运输。

许多产品,如染料,显示出一定的光敏性。但是,除非在产品页面上另有规定,对光线的敏感性是很小的,没有必要使用暗包装,或在黑暗中工作。然而,应该避免直接暴露在阳光下(因为太阳光含有很大一部分紫外线,而这种紫外线对荧光的危害更大)。应限制环境光的曝光–不要让染料在环境光中停留数天或数周。

有些产品,如国民保健服务的酯,是由大气中存在的水水解的,特别是在潮湿的环境中。当试剂从冰箱中取出时,必须在打开前将瓶加热到室温。否则,大气湿度会立即凝结在瓶内的冷壁上,并在关闭后保持在那里,降低试剂架的寿命。在使用该试剂后,当可能的话,在关闭小瓶之前用惰性气体(干氮或氦)清除小瓶–这将延长试剂架的使用寿命。在净化粉体时,如氰化染料的国民健康服务酯,要小心气体流量,因为强气体射流可以将气载粉体从瓶中取出。
