O-Acetylserine (OAS) serves as the carbon skeleton for cysteine production and is a key metabolite of sulfur absorption. Cysteine is formed when OAS absorbs sulfide, which is produced when sulfate reacts. Regardless of the sulfate status of the plant, OAS has a signaling role that causes modifications in the transcript levels of particular genomes [1]. The transcriptional induction model of OAS is in line with the increased expression of the sulfate transporter and adenosine 5'-phosphate reductase genes after external OAS treatment [2].

Additional Infomation |
O-acetyl-L-serine is an acetyl-L-serine where the acetyl group is attached to the side-chain oxygen. It is an intermediate in the biosynthesis of the amino acid cysteine in bacteria. It has a role as a bacterial metabolite and a Saccharomyces cerevisiae metabolite. It is an acetate ester and an acetyl-L-serine. It is a tautomer of an O-acetyl-L-serine zwitterion.
O-Acetylserine is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). O-acetyl-L-serine has been reported in Daphnia pulex, Arabidopsis thaliana, and other organisms with data available. |

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 0.62 mg/mL (4.21 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 6.2 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 0.62 mg/mL (4.21 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 6.2 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. 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. View More
Solubility in Formulation 3: ≥ 0.62 mg/mL (4.21 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. Solubility in Formulation 4: 100 mg/mL (679.67 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication. |

*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.
Calculation results
Working concentration: mg/mL;
Method for preparing DMSO stock solution: mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation::Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
