体外実験

Guidelines (The following is our recommended protocol. This protocol is provided for reference only and should be modified according to your specific needs).
Texas Red (Sulforhodamine 101) can be used as an astrocyte marker for hippocampal slices staining with red fluorescence^[3].
For cell staining.
1. Stain hippocampal slices with Texas Red (5 μM; 35 min; 34°C) in carbogenated Artificial CerebroSpinal Fluid (ACSF).
2. Return hippocampal slices to dye-free ACSF for at least 30 min before imaging.
3. Use a confocal laser scanning microscopy (Zeiss LSM 880) for image.

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

体内実験

In vivo, epileptic activity can be induced by intra-hippocampal injection of small volumes of 10 μM Texas Red or topical application of 100 μM^[1].

Help & FAQs

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.
