In Vitro

Hypoxanthine is a potential free radical generator. Hypoxanthine seems to play a role in posthypoxic reoxygenation cell injury through oxygen radical production and is therefore involved in the pathogenesis of a number of diseases. Hypoxanthine also modulates a number of other processes because it reacts with benzodiazepine receptors and inhibits phosphodiesterase in the brain. Hypoxanthine inhibits the effect of several cytotoxic drugs and may therefore influence treatment with such drugs^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

In pigs, a linear increase of plasma hypoxanthine with duration of hypoxemia is found, and there is no difference between arterial and venous plasma. There are good correlations between hypoxanthine and lactate, base deficit and pH. There is also a direct relationship between survival time and increase in plasma hypoxanthine. Survival time correlates negatively with the rate of hypoxanthine increase (r=-0.62).All animals die when hypoxanthine exceeds 125 pM/liter. The increase of hypoxanthine therefore reflected the prognosis of acute hypoxia in contrast to base deficit^[1].

Stock Solution Working Solution

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.

Protocol 1

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 1 mg/mL (7.35 mM); Clear solution

This protocol yields a clear solution of ≥ 1 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 2

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 1 mg/mL (7.35 mM); Clear solution

This protocol yields a clear solution of ≥ 1 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Working Solution

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.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
