일반 설명

Phosphatidylserine is an anionic phospholipid, which is found on the plasma membrane.[1] Exposure of phosphatidylserine on the surface of plasma membrane stimulates the removal of apoptotic and red blood cells.[2] It regulates the production of thrombin and maintains hemostasis.[3]

애플리케이션

3-sn-Phosphatidyl-L-serine sodium salt from bovine brain has been used as a glycosylphosphatidylinositol (GPI)-anchor control.[3]

생화학적/생리학적 작용

A slowly metabolized structural phospholipid found mainly in gray matter.

주의사항

Solutions exposed to room temperature will decompose about 0.5% per day.

제조 메모

Washed with EDTA and converted to a sodium salt.

질문

1–7 / 7 질문  

  1. What is Product P5660, 3-sn-Phosphatidyl-L-serine sodium salt, commonly used for?

    1 답변

    1. Phosphatidylserine is important in enzymatic assays of purified protein kinase C. During activation of this enzyme, as part of the signal transduction process, phosphatidylserine, which is located on the inside of cellular plasma membranes, binds to cysteine residue domains on protein kinase C. Phosphatidylserine can be used as a standard in thin-layer chromatography and for artificial membrane studies such as in lipsome research.

  5. What is the molecular weight of Product P5660, 3-sn-Phosphatidyl-L-serine sodium salt from bovine brain?

    1 답변

    1. The molecular weight of this compound is approximately 812.1 g/mole. This molecular weight assumes that stearoyl and oleoyl are the prodimant fatty acids in the compound.  Phosphatidylserine may have a number of different fatty acid residues associated with it.  Our analyses of multiple lots of phosphatidylserine identified average fatty acid percentages of approximately 40% for stearic acid and 30% for oleic acid.

  7. What is the solution stability of Product P5660, 3-sn-Phosphatidyl-L-serine sodium salt from bovine brain?

    1 답변

    1. Solutions can be divided into aliquots and stored at -20 °C. We have no information as to how long the solutions will be stable. Solution stability is enhanced when the compound is protected from oxygen, because the unsaturated fatty acids are subject to oxidation. To protect from oxidation, dissolve the compound in solvents in which oxygen has been removed and replaced with an inert gas such as nitrogen or argon.
