|Kit Includes||Petite Kit (P) Quantity||Small Kit (S) Quantity|

To prepare the DAB working solution, add 1 drop (30 μl) SignalStain® DAB Chromogen Concentrate to 1 ml SignalStain® DAB Diluent and mix well before use. Working solutions are stable for up to 14 days when stored at 4ºC or up to 5 days when stored at room temperature (approximately 25ºC). While the solution may change color over that time period, it will have no effect on the quality of the staining.
*Please note that when using 8059P, a dropper for the chromogen concentrate is not included. Use a pipet to add 30 μl of SignalStain® DAB Chromogen Concentrate to 1 ml SignalStain® DAB Diluent.
Important: DAB is a suspected carcinogen. Good laboratory practices should be followed, and appropriate protective equipment should be used when handling DAB, including gloves, protective eyeware, and a lab coat. Dispose in accordance with local regulations.
After incubation with SignalStain® Boost IHC Detection Reagent or other HRP-based detection systems, wash slides and incubate with the working solution at room temperature until staining develops. 1-10 minutes generally provides an acceptable staining intensity.
Wash slides in water for 5 minutes.
Counterstain, if desired, and mount coverslips with either a permanent mounting media or an aqueous-based mounting media. Please note, permanent mounting requires dehydration through ethanol and clearing through xylene.
Each SignalStain® DAB Substrate Kit includes enough DAB Diluent and DAB Chromogen Concentrate to stain either 1200 (#8059S) or 120 (#8059P) slides.
Substrate kit should be stored at 4ºC, protected from light. Each kit is stable for 12 months upon receipt if the reagents are not combined.
