Protein disulfide isomerase cleaves allosteric disulfides in histidine-rich glycoprotein to regulate thrombosis. [Abstract]2024 Apr 11;15(1):3129. PMID: 38605050
Eptifibatide purchased from MedChemExpress. Usage Cited in: Nat Commun. 2024 Apr 11;15(1):3129. [Abstract]
The median fluorescence intensity of HRG and platelets were calculated and plotted over time from mice treated or untreated with Eptifibatide (10 μg/g body weight, repeated every 15-20 min).
Eptifibatide purchased from MedChemExpress. Usage Cited in: Nat Commun. 2024 Apr 11;15(1):3129. [Abstract]
The scatter plot of pixel intensities of green (HRG) and red (CD31) fluorescence in ROI1 and ROI2 as indicated were presented. The Pearson's correlation coefficients (r) for pixels with intensity above the threshold (indicated by the dashed lines) in the thrombus (ROI2) and in the area without the thrombus (ROI1-ROI2) were inserted. Veh vehicle, Epti eptifibatide.
Eptifibatide purchased from MedChemExpress. Usage Cited in: Nat Commun. 2024 Apr 11;15(1):3129. [Abstract]
When mice were treated with eptifibatide, an integrin αIIbβ3 antagonist that eliminated platelet deposition and thus platelet-derived Zn2+, HRG accumulation at the site of vessel injury was significantly reduced by 58.3%.

Solvent & Solubility
DMSO : 200 mg/mL (240.40 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 50 mg/mL (60.10 mM; Need ultrasonic)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture and light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (2.50 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (2.50 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
