Biological Activity
| ln Vitro | SAPE uses ultrasonic oscillation of microspheres in conjunction with tumor companion diagnostic factor capture antibodies for a duration of 20 seconds in order to detect tumors [1]. (2) Maintain microspheres in assay buffer at a 50 microspheres/µL final concentration. Pour 50 µL of the detection buffer and 50 µL of the standard as a control into each well of the 96-well plate. (3) Incubate at 800 rpm/min for 30 minutes at room temperature. (4) After 30 to 60 seconds on the magnetic separation plate, filter out the supernatant and repeat the washing process twice, using 100 μL of reaction buffer each time. Fifth, thoroughly mix in 50 µL of detection buffer. (6) Add 50 µL to each well after diluting the biotinylated detection antibody with detection buffer to 4 µg/mL. (7) Incubate at 800 rpm/min for 30 minutes at room temperature. (8) After 30 to 60 seconds on the magnetic separation plate, remove the supernatant and wash twice, using 100 μL of reaction buffer each time. Add 50 µL of detection buffer and thoroughly mix. (10) Add 50 µL to each well after diluting SAPE with detection buffer to 4 µg/mL. (11) Incubate at 800 rpm/min for 30 minutes at room temperature. Once the magnetic separation plate has been placed on it for 30 to 60 seconds, remove the supernatant and wash twice, using 100 μL of reaction buffer each time. (13) Include 100 µL of detection buffer and thoroughly stir. (14) Luminex magnetic microspheres' fluorescence encoding signal and SAPE's reporter fluorescence signal should be excited. A high-sensitivity CCD imaging device or flow analysis device and software should then be used to perform Luminex magnetic microsphere classification and result detection using a particular algorithm. |

| Additional Infomation | 1-stearoyl-2-arachidonoyl-sn-glycero-3-phosphoethanolamine zwitterion is a phosphatidylethanolamine 38:4 zwitterion obtained by transfer of a proton from the phosphate to the primary amino group of 1-octadecanoyl-2-(5Z,8Z,11Z,14Z-icosatetraenoyl)-sn-glycero-3-phosphoethanolamine; major species at pH 7.3. It is a phosphatidylethanolamine 38:4 zwitterion and a 1-stearoyl-2-acyl-sn-glycero-3-phosphoethanolamine zwitterion. It is a tautomer of a 1-stearoyl-2-arachidonoyl-sn-glycero-3-phosphoethanolamine. |
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. 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.

Oral Formulation 3: Dissolved in PEG400 Oral Formulation 4: Suspend in 0.2% Carboxymethyl cellulose Oral Formulation 5: Dissolve in 0.25% Tween 80 and 0.5% Carboxymethyl cellulose Oral Formulation 6: Mixing with food powders Note: Please be aware that the above formulations are for reference only. 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.) |
