I can confirm that on the individual datasheets, we list the applications and species that have been tested. These are covered by the Abpromise guarantee.  If there are any species or applications not listed, it means they have not yet been tested. If they have been tested but found not to be successful (which happens very rarely), we will also add a note to state this.

Therefore, I can confirm that ab66218 has not yet been tested in mouse.

Regarding the flow cytometry protocol for ab214369Anti-APJ Receptor antibody, I have copied the general flow cytometry procedure from the testing laboratory below. Please note this will be a guideline only and may require some individual optimization.

Flow Cytometry Protocol

Harvest and wash the cells and determine the total cell number.

Resuspend the cells to approximately 1x106 cells/mL in ice cold PBS. Add the appropriate volume of paraformaldehyde to obtain a final concentration of 4%.

Fix for 10 minutes in a 37°C water bath.

Wash cells twice with PBS containing 0.5% BSA.

Note: For extracellular staining with antibodies that do not require permeabilization, proceed to step 8; for intracellular staining, proceed to step 5.


Add ice-cold 90% methanol (approximately 1mL per 1x106 cells) and vortex.

Permeabilize for a minimum of 10 minutes on ice.

Immunostaining and Analysis

Wash cells twice with PBS containing 0.5%BSA.

Resuspend 1x106 cells in 100μL PBS containing 0.5%BSA.

Add the primary antibody and incubate for 1 hour at room temperature (RT).

Wash cells twice with PBS containing 0.5%BSA.

Note: If using a fluorescent primary conjugated antibody, skip to step 14.

Resuspend cells in fluorochrome conjugated secondary antibody diluted in PBS containing 0.5% BSA.

Incubate for 30 minutes at RT.

Wash cells twice with PBS containing 0.5% BSA.

Resuspend cells in 0.5mL PBS and analyze on flow cytometer.
