AEC (3-amino-9-ethylcarbazole), anHRP substrate, produces a red reaction product that can be used as a single label or as a second color for multiple antigen labeling. AEC chromogens can be used for both manual and automated staining procedures. Stained slides must be mounted in aqueous media because AEC reaction products are soluble in organic solvents. ThisKit contains stock solutions in convenient dropper bottle for immunochemistry applications and provides all ofall the necessary reagents to prepare about 300 mL of working solution which can also be used for Western blotting applications. When stored at 4â€šÃ Ã¶âˆšÃ†â€šÃ Ã¶â€šÃ Ã¨â‰ˆÃÂ¬Â©C, thisKit is stable for up to one year.
