Aladdin ® 640-4SE (Aladdin ® 640-4 succinimidyl ester)

Product introduction：Aladdin ® SE (or NHS ester) is a kind of fluorescent dye with amino reaction activity produced by our company.SE groups of these dyes can react with amino groups to produce stable amide bonds. Compared with other similar dyes on the market, Aladdin ® It is a new generation of fluorescent dyes with stronger stability, better water solubility and better fluorescence intensity. Our company also provides a small batch of antibody labeling kit Aladdin ® Antibody labeling kits (s6011), which can label 5-100 in 30 min μ G antibody without purification steps, which is simple and convenient.Matters needing attention：1. if the labeled protein needs long-term storage, it is recommended to add 5-10 mg/ml BSA and 0.01-0.03% NaN3 to prevent protein denaturation and microbial breeding. Store at 4 ℃ away from light. If glycerol with a final concentration of 50% is added, it can be stored at -20 ℃. It can be stably stored for more than one year. 2. keep away from light during operation. The mixing speed should be appropriate to avoid bubbles. 3. when installing the chromatographic column, try to make the column body uniform, the column surface flat, and free of bubbles and cracks. 4. pay attention to adding the sample when the column top buffer is tangent to the gel plane. When eluting, add the eluent when the sample is tangent to the gel plane. 5. other factors affecting the labeling efficiency also include temperature, reaction time, pH, the amount of fluorescent dye and protein, etc., which should be controlled. 6. for your safety and health, please wear laboratory clothes and disposable gloves.Scope of application：Protein nucleic acid labeling dye.
