Lumiprobe Cy荧光染料试剂保存方法

Lumiprobe Corporation是美国一家高品质生物技术公司，专业提供分子生物学研究用的活性荧光染料。从2006年开始，公司生产并销售生命科学研究和诊断学应用的优质化学药品。产品主要有：活性染料(Reactive Dye)和SYBR Green I 染料，用于寡核苷酸合成的亚磷酰胺，点击化学用染料和其它试剂。 产品主要应用：点击化学(Click Chemistry)、蛋白质组学研究中的双向荧光差异凝胶电泳(2D DIGE)和实时荧光定量PCR(Realtime PCR)。

作为Lumiprobe代理，上海金畔生物生物可提供Lumiprobe的完整产品线，满足您的各种科研实验需求。产品包括：羧酸类染料、羰基类染料，标记分子氨基活性染料，标记分子巯基活性染料，动物活体成像用染料，蛋白质、多肽、核酸等生物分子标记染料、点击化学等。渠道正规（市场上部分是分装，质量不能保证），质量保证，价格极具竞争力,而且我们的货期进需要3-5工作日，不需要像其他家攒单货期3-4周。

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 refridgerator, 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.
