In Vitro

The efficacy of Ethosuximide in generalized absence epilepsy is thought to be due to blockade of the low voltage activated T-type calcium channel. There is no reduction in total Tau levels in Ethosuximide treated Tau transgenic worms as compare to vehicle controls. The rescuing effect of Ethosuximide is therefore not due to transgene suppression or reduced expression of toxic mutant Tau protein. Quantification of the amount of soluble and insoluble (RIPA-extractable) Tau relative to total Tau levels reveals a significant reduction in aberrantly-folded, insoluble Tau and a corresponding increase in soluble Tau in Ethosuximide-treated compare with untreated worms^[1]. Concentrations of 2 μM or more of Ethosuximide not only are found to be less effective than 1 μM concentration of Ethosuximide, but also induce cell toxicity. GABA staining immuno uorescence images show that after treatment with Ethosuximide, GABA positive neuron increases by 3 and 6.5 fold for concentrations of 0.1 and 1 μM, respectively. BrdU staining shows nuclei proliferation after 2 to 3 days of Ethosuximide exposure. The mean of nuclei is 15.98±0.41 for the low concentration of Ethosuximide while it is 25.27±0.48 for the high concentration after Brdu staining. This number is 11.05±0.2 for lithium chloride^[2].

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 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2.08 mg/mL (14.73 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.

Protocol 2

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

Solubility: ≥ 2.08 mg/mL (14.73 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.

Protocol 3

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

Solubility: ≥ 2.08 mg/mL (14.73 mM); Clear solution

This protocol yields a clear solution of ≥ 2.08 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 (20.8 mg/mL) to 900 μL Corn oil, and mix evenly.

Protokoll

Kinase Assay^[1]

Vehicle- and Ethosuximide-treated Tau V337M worms are lysed and separated into soluble and insoluble fractions. Fractions are separated by SDS-PAGE and western blotted using anti-human Tau T46 and anti-actin antibodies. The abundance of Tau protein in each fraction is quantified by densitometry and normalized against beta-actin. Total Tau levels in lysates are expressed as the percentage of actin-normalized Tau relative to vehicle control lysates; Tau levels in sequentially extracted fractions are expressed as the percentage of actin-normalized Tau relative to the sum of both fractions (soluble+RIPA) combined^[1].

Cell Assay

Neuronal stem cells from the forebrain Cortex of a 3-day-old rat are used in this study. The cells are differentiated by withdrawal of basic ﬁbroblastic growth factor (bFGF) and exposed to Ethosuximide at two concentrations of 0.1 μM and 1 μM. Before drug treatment, the cells are rinsed once with PBS, and the medium is replaced with fresh, bFGF-free DMEM/F12 medium containing different concentration of Ethosuximide. Medium exchange is done every day for 6 days with medium containing Ethosuximide. Then, cells are ﬁxed for immunocytochemistry^[2].

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.
