LDS-751
Based on 1 Customer Validation
Lds-751 is a nucleic acid stain that mainly detects DNA. Lds-751 is a nucleic acid stain that mainly detects DNA. Lds-751 has a high affinity for DNA and fluorescence is enhanced after binding, but the maximum emission wavelength is 670nm. Lds-751 and Thiazole orange can be used for the differentiation of red blood cells, platelets, reticulocytes, and nucleated cells and can be stimulated at 488nm. Studies have shown that LDS-751 binds almost exclusively to mitochondria when incubated with nucleated living cells. After nucleated Acridine Orange (HY-101879) staining and LDS-751 treatment of cells, confocal microscopy revealed almost no co-location of the cells. Staining with Rhodamine 123 (HY-D0816), a dye known to bind polarized mitochondria, was almost identical to the pattern observed with LDS-751.

Guide (The following is our recommended protocol. This protocol is only a guide and should be modified according to your specific needs).
1.Preparation of LDS-751 working solution
1.1 Preparation of the stock solution:
Prepare LDS-751 stock solution with DMSO.
1.2 Preparation of LDS-751 working solution:
Dilute the stock solution in serum-free cell culture medium or PBS to obtain working solution.
Note: Please adjust the concentration of Lds-751 working solution according to the actual situation.
2. Cell staining
2.1 Cell preparation
For suspension cells: Centrifuge at 1000 g at 4°C for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time.
For adherent cells: Discard the cell culture medium, and add trypsin to dissociate cells to make a single-cell suspension. Centrifuge at 1000 g at 4°C for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time.
2.2 Fix cells with 3.7% formaldehyde for 10 minutes, discard the fixative and rinsed with PBS for three times, 5 minutes each time.
2.3 Permeate cells with 0.2% Triton X-100 for 5 minutes, wash three times with PBS, 5 minutes each time.
2.4 Add 1 mL of LDS-751 working solution, and then incubate at room temperature for 1-5 minutes.
2.5 Centrifuge at 400 g at 4°C for 3-4 minutes and then discard the supernatant.
2.6 Wash twice with PBS, 5 minutes each time.
2.7 Resuspend cells with serum-free cell culture medium or PBS, and then detect by fluorescence microscope or flow cytometer.
3. Precautions
3.1 It is recommended to store the stock solution at -20℃ or -80℃ away from light and avoid repetitive freeze-thaw cycles.
3.2 Detect the fluorescence as soon as possible to avoid fluorescence quenching.
3.3 It is recommended to use AntiFade Mounting Medium (MCE Cat. No.: HY-K1042) to slow the fluorescence quenching.
3.4 Please adjust the concentration of LDS-751 working solution according to the actual situation.

プロトコル
Blood samples (1 mL) are obtained using a sterile Butterfly-21 needle and plastic syringe from the antecubital vein of normal healthy volunteers who have given their informed consent. They are immediately transferred to plastic tubes containing 17.3 mg of phenylmethylsulphonyl fluoride (PMSF) and 1 mL of LDS-751 at room temperature. Aliquots (25 μL) are incubated for 5 min with between 2 μL and 5 μL of undiluted monoclonal antibodies, then diluted with 0.5 mL of 1% BSA in Hepesbuffered Hanks' balanced salts solution (HHBSS) and examined by flow cytometry[2].
