C6 NBD Ceramide is a cell membrane permeable/penetrable Golgi fluorescent probe (Ex=466 nm, Em=536 nm). C6 NBD Ceramide can quickly and conveniently label the Golgi apparatus with green fluorescence in living cells and fixed cells, and may be utilized to observe changes in Golgi apparatus morphology in living cells. C6 NBD Ceramide can be metabolized into fluorescent sphingomyelin and glucosylglyceramide, which may be utilized to study sphingolipid transport and metabolic mechanisms.

Biological Activity

ln Vitro	Advice (This is our suggested protocol, which should be adjusted to suit your particular circumstances as it simply offers guidance). Golgi tagging [3]: 1. Cells on coverslips should be rinsed with HMEM before being fixed for five to ten minutes at 25°C with either glutaraldehyde or paraformaldehyde. 2. Use a balanced salt solution (HCMF, for example) to wash the fixed cells. 3. Place the culture plate with the glass coverslip in an ice-water bath and incubate it for 3 × 5 minutes (for cells that have been glutaraldehyde-fixed) using freshly made NaBH4. 4. Rinse cells multiple times (20–30 minutes) in cold HCMF, then preheat to 25°C and incubate for 60 minutes in the presence of C6 NBD-Ceramide/BSA. 5. Cleansed fixed cells with HCMF, incubate (30-90 minutes; 25°C) with 10% fetal bovine serum or 2 mg/mL BSA to improve Golgi apparatus dyeing equipment and counter-exchange excess C6 NBD-ceramide in the preparation. 6. Using a fluorescence microscope (E=536 nm, Ex=466 nm), mount the glass coverslip on the recessed slide and examine.

Additional Infomation	N-{6-[(7-nitro-2,1,3-benzoxadiazol-4-yl)amino]hexanoyl}sphingosine is an N-acylsphingosine that is sphingosine with the amino nitrogen converted into a 6-{[N-(7-nitrobenzo-2,1,3-oxadiazol-4-yl)amino]}hexananamido group. It has a role as a fluorescent probe.

Solubility Data

Solubility (In Vitro)

May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples

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.

InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.  (Please use freshly prepared in vivo formulations for optimal results.)

Preparing Stock Solutions		1 mg	5 mg	10 mg

*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.
