RAL DIFF-QUIK™

RAPID
RAL Diff-Quik is a simplified and cost-effective alternative to Wright-Giemsa staining and is faster than typical staining procedures. It reduces the process from 4 minutes to 15 seconds. The speed of execution makes it an ideal stain for emergency diagnostics of medullary and bloods smears.

EASY
This 3-step method is very easy. It consists of 3 brief immersions in each of the RAL Diff-Quik solutions. This manual protocol allows the user to customise and vary the staining intensity. The different degrees of shading allow RAL Diagnostics to deliver preferential staining to every lab.

READY-TO-USE

A new packaging has been created for direct staining without the need to decant stains.

Features & Benefits

RAL Diff-Quik

CONVENIENT PACK SIZES

  • RAL Diff-Quik EZ-KIT (3 x 100 mL) - for manual “Dip and Dunk” staining - Includes 3 wide necked bottles to allow the user to directly dip the slides into vials without any transfer of chemicals.
  • RAL Diff-Quik STAIN SET (3 x 0.5 L)
  • RAL Diff-Quik – Fixative, Solutions 1 and 2 in individual bulk (2.5L) containers.

QUALITY STAINING
User configurable - The different degrees of shading allow RAL Diff-Quik to deliver preferential staining to every lab.
The nuclei are stained red to purple (meta-chromatically) by the azure component of the dye mixture. It is believed that DNA is capable of functioning as a chromotope for Azure A, B and methylene violet.
The xanthene solution stains cytoplasm pink to yellowish-red.

Each kit contains:

RAL Diff-Quik fixative solution
It fixes air-dried blood smears. This methanol based solution will stabilise cellular components. Solution I and II are applied individually to the fixed smear to differentially stain specific cellular components.

RAL Diff-Quik solution I (Xanthene solution)
A buffered solution of Eosin Y (an anionic dye)

RAL Diff-Quik solution II
Solution II is a buffered solution of thiazine dyes (cationic dyes) consisting of methylene blue and Azure A. The resultant basophilic staining of nucleoli and cytoplasm is due to the methylene blue component of the mixture. The anionic component of the nucleoli and cytoplasm, which is stained with the cationic methylene blue, is presumed to be RNA.
