Example protocol
PREPARATION OF STOCK SOLUTIONS
Unless otherwise noted, all unused stock solutions should be divided into single-use aliquots and stored at -20 °C after preparation. Avoid repeated freeze-thaw cycles
Add 500 µL of ddH2O into the powder form to make a 2 mg/mL stock solution.
Note: The reconstituted conjugate solution can be stored at 2-8 °C for short-term storage or at -20 °C for long-term storage.
PREPARATION OF WORKING SOLUTION
Add 5 µL of 200X WGA conjugate solution to 1 mL HHBS Buffer.
Note: The optimized staining concentration may be different with different cell lines. The recommended starting concentration is 5-10 µg/mL for live cells.
SAMPLE EXPERIMENTAL PROTOCOL
Warm the vial to room temperature centrifuge briefly before opening. Staining protocols vary with applications. Appropriate dilution of conjugates should be determined experimentally.
- Wash cells twice with a HHBS buffer.
Add 100 µL iFluor® 680-WGA working solution.
- Incubate cells with WGA working solution for 10-30 minutes at 37 °C.
- Wash cells twice with HHBS buffer.
Image cells on a fluorescence microscope using Cy5 filter set.
WGA conjugates can be also used to stain fixed cells.
Fix cells with 4% Formaldehyde in PBS.
Note: For fixed cell membrane staining, it is recommended to stain without the permeabilization step. A permeabilization step after fixation can facilitate staining intracellular compartments such as Golgi and Endoplasmic Reticulum (ER) structures.
Add 100 µL iFluor® 680-WGA working solution.
- Incubate cells with WGA working solution for 10-30 minutes at room temperature.
- Wash cells twice with HHBS buffer.
