BODIPY 558/568 C12 is a BODIPY dye. BODIPY dye is a small molecule dye with strong UV absorption ability. Its fluorescence peak is relatively sharp and its quantum yield is high. It is relatively insensitive to the polarity and pH of the environment and, therefore, is relatively stable under different physiological conditions. Due to the asymmetry of its structure, BODIPY has a variety of analogue structural products. BODIPY lipid droplet dye can penetrate the cell membrane well into the interior of the cell and perform specific staining by localizing on the polar lipids in the cell. Therefore, the dye may be utilized to label living cells and fixed cells. Maximum excitation/emission wavelength: 558/568 nm.

Biological Activity

ln Vitro

Guidelines for usage 1. 1.1 Prepare the stock solution for BODIPY558/568C12 preparation. To make a 10 mM stock solution, dilute 1 milligram of BODIPY558/568C12 with 382 μL of anhydrous DMSO. Note: The BODIPY558/568C12 storage solution should be aliquoted and kept at -20°C or -80°C in the dark. 1.2 Making the working solution Prepare a 1–10 μM BODIPY558/568C12 working solution using either hot serum-free cell culture medium or diluted PBS storage solution. Note: Please prepare the BODIPY558/568C12 working fluid for usage by adjusting its concentration to suit the current circumstances. 2. Suspended cell staining (2.1): Centrifuge cells, add PBS, then wash twice for five minutes each time. 2.2 Add 1 mL of BODIPY558/568C12 working solution and incubate at room temperature for 5-30 minutes, or until the cell density reaches 1×106/mL. 2.3 Centrifuge at 400g for 3–4 minutes, discarding the supernatant. 2.4 After adding PBS, wash the cells twice for five minutes each. 2.5 Re-suspend the cells in 1 milliliter of PBS or serum-free media, and use a flow cytometer or fluorescence microscope to observe. 3. Adherent cell staining (3.1): Grow adherent cells on sterile coverslips. 3.2 Aspirate extra culture medium after removing the coverslip from the medium. 3.3 Cover the cells fully with 100 μL of the dye working solution, shake gently, and allow incubate for five to thirty minutes. 3.4 Aspirate the dye working solution, rinse with culture medium two or three times for five minutes each, and use a flow cytometer or fluorescence microscope to monitor. Storage temperature: -20°C, sealed against light for a year. Observations 1. Please modify the BODIPY558/568C12 working solution's concentration and incubation period to reflect the current circumstances. 2. It is advised that the experiment include a positive control. Before performing the next tests, incubate the cells in the control group with 30 μM oleic acid for 8 hours. 3. This product may not be used for clinical diagnosis or treatment, nor may it be included into food or medication. It is intended solely for professional use in scientific study. 4. Please wear disposable gloves and a lab coat for your health and safety.

Solubility (In Vivo)

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples. Injection Formulations (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
