Py-BODIPY-NHS ester

CAS No. : 201998-61-0

MCE 国际站：Py-BODIPY-NHS ester

产品活性：BODIPY 染料是一种具有强紫外吸收能力的小分子染料，其荧光峰比较尖锐，量子产率高。其对环境的极性和 pH 值相对不敏感，因此，在不同生理条件下相对稳定。由于其结构的非对称性， BODIPY 具有多种衍生结构产物。BODIPY 脂滴类染料可以很好的穿过细胞膜进入细胞内部，通过在细胞内的极性脂类上定位以进行特异性染色，因此，该染料可用于标记活细胞和固定细胞。

研究领域：Others

作用靶点：Fluorescent Dye

In Vitro: General Protocol (Example for Py-BODIPY NHS ester)
1.Preparation of Py-BODIPY NHS ester working solution
1.1Preparation of the stock solution
Dissolve 1 mg Py-BODIPY NHS ester in 382 μL DMSO to obtain 10 mM of stock solution.
Note: It is recommended to store the stock solution at -20 ℃ -80 ℃ away from light and avoid repetitive freeze-thaw cycles.
1.2Preparation of BODIPY 493/503 working solution
Dilute the stock solution in serum-free cell culture medium or PBS to obtain 1-10 μM of working solution.
Note: Please adjust the concentration of Py-BODIPY NHS ester working solution according to the actual situation.
2.Cell staining
2.1 Suspension cells (6-well plate)
a.Centrifuge at 1000 g at 4℃ for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time.The cell density is 1×10⁶mL.
b.Add 1 mL of working solution, and then incubate at room temperature for 5-30 minutes.
c.Centrifuge at 400 g at 4℃ for 3-4 minutes and then discard the supernatant.
d.Wash twice with PBS, 5 minutes each time.
e.Resuspend cells with serum-free cell culture medium or PBS. Observation by fluorescence microscopy or flow cytometry.
2.2 Adherent cells
a. Culture adherent cells on sterile coverslips.
b. Remove the coverslip from the medium and aspirate excess medium.
c. Add 100 μL of working solution, gently shake it to completely cover the cells,and then incubate at room temperature for 5-30 minutes.
d. Wash twice with medium, 5 minutes each time.Observation by fluorescence microscopy or flow cytometry.
