The Golgi apparatus is composed of flat sacs made of unit membranes stacked together. Flat sacs are round with dilated edges and perforations. The Golgi fluorescent probe is a BODIPY-labeled ceramide analogue. The synthesis of ceramide occurs in the endoplasmic reticulum, and the Golgi fluorescent probe can be transported to the Golgi via ceramide transporter (CERT) or vesicular transport, thereby achieving specific labeling of the dye. BODIPY Fl C5-Ceramide is a Golgi-specific green fluorescent dye that enables single cell visualization. Ex/Em=505 nm/512 nm.

Biological Activity

ln Vitro

Guidelines for usage 1. Ingredients for the Golgi working solution 1.1 Make a 5 mM stock solution with DMSO. Note: To prevent recurrent freeze-thaw cycles, it is advised to store the stock solution at -20°C or -80°C in the dark. 1.2 To create a 1–10 μM Golgi working solution, utilize previously produced PBS or culture medium solution. Note: Please prepare Golgi 1-43 working solution for use by adjusting its concentration to suit the current circumstances. 2. Suspension cell staining (2.1): Gather cells at 1,000 g, 4°C, centrifuge for three to five minutes, and remove the supernatant. After adding PBS, wash for five minutes each time. The density of cells is 1×106/mL. 2.2 Add one milliliter of the Golgi working solution (2.3 400 g, 4°C), centrifuge for three to four minutes, and then remove the supernatant. 2.4 Wash the cells twice with PBS, giving them five minutes each time. 2.5 Observe using a flow cytometer or fluorescence microscope after resuspending the cells in 1 mL of serum-free bone marrow or PBS. 3. Adherent cells for staining 3.1 Adherent cells are cultured on sterile coverslips. 3.2 Take off the cell coverslip, aspirate 3.3, add 100 μL of the dye working solution, and shake for 20 to 30 minutes to cover the cells thoroughly. 3.4 Aspirate out the dye working solution, wash twice in culture media for five minutes each time, then use a flow cytometer or fluorescence microscope to monitor. Storage conditions: -20°C for a year, with protection from light. Precautions: 1. The storage solution should be kept out of direct sunlight, at a temperature of -20°C or -80°C, and not frozen and thawed too frequently. 2. Please modify the Golgi 1-43 working solution's concentration and dilution duration to reflect the current circumstances. 3. Alternatively, the diluent Hanks balanced salt solution can be used for washing if the results of utilizing cells are not satisfactory and the cell culture medium is reached. 4. This product should not be used for clinical diagnosis or treatment, nor should it be included into food or medication. It is intended solely for professional use in scientific study. 5. Please wear a lab coat and a snap shot operation 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. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals). Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] *Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline 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.
