| Description | Systemin acetate is an 18-amino acid polypeptide with the sequence AVQSKPPSKRDPPKMQTD that is found in Solanaceae plants (such as tomato and potato). |
| In vitro | Systemin is readily transported from wound sites and is considered to be the primary systemic signal.The signal transduction pathway that mediates Systemin signaling involves linolenic acid release from membranes and subsequent conversion to jasmonic acid, a potent activator of defense gene transcription. The pathway exhibits analogies to arachidonic acid/prostaglandin signaling in animals that leads to inflammatory and acute phase responses[1]. Systemin, an 18-amino-acid peptide signal. Systemin is cleaved from the C-terminal region of a 200-amino acid precursor protein called proSystemin. Following the cloning of proSystemin gene, which represents a single locus in the tomato genome, several lines of genetic evidence indicate that Systemin acts as an upstream component of wound-induced signaling cascades leading to defense gene expression[2]. |

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 
10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.Stock Solution Preparation:
Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
Preparation of the In Vivo Formulation:
1) Add 100 μL of the DMSO stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O and mix thoroughly until a homogeneous solution is obtained.
This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.
