Additional Infomation 1-stearoyl-2-arachidonoyl-sn-glycero-3-phospho-1D-myo-inositol 4,5-biphosphate is a 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate in which the phosphatidyl acyl groups at positions 1 and 2 are specified as stearoyl and arachidonoyl respectively. It is functionally related to an arachidonic acid and an octadecanoic acid. It is a conjugate acid of a 1-stearoyl-2-arachidonoyl-sn-glycero-3-phospho-1D-myo-inositol 4,5-biphosphate(5-).
Phosphatidylinositol 4,5-bisphosphate is a phospholipid that is a component of the plasma membrane with signal transduction inducing activity. Phosphatidylinositol 4,5-bisphosphate (PIP2) is an intermediate that can be converted into either the second messenger signaling molecules, inositol 1,4,5-trisphosphate (IP3) and diacylglycerol (DAG), or phosphatidylinositol (3,4,5)-trisphosphate (PtdIns(3,4,5)P3; PIP3). Both PIP2 and PIP3 can act as docking phospholipids, which recruit signaling proteins to the plasma membrane and promotes the activation of several signaling cascades.

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)

Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).
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.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 0.9550 mL 4.7751 mL 9.5503 mL

10 mM 0.0955 mL 0.4775 mL 0.9550 mL
*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.
