- Dip slide or tape-strip five times, for one second each, into Stain 2.

Which stain is used first in the diff quick method?
The primary use of Romanowsky-type stains in cytopathology is for cytoplasmic detail, while Papanicolaou stain is used for nuclear detail.
Is Diff-Quik a Gram stain?
Diff-Quik stain, a variant of Romanowsky stain, is used to quickly identify cells and bacteria. However, it does not differentiate between gram-positive or gram-negative bacteria. Diff-Quik consists of a fixative (methanol) and eosinophilic (orange) and basophilic (purple) counterstains.
What is the procedure of Leishman stain?
1) Freshly prepare and rapidly air dry blood film. 2) Cover the film with Leishman’s Stain (S018S) and allow to act for 1 minute. Methanol in the stain fixes the preparation. 3) Add double the volume of distilled water to the slide and mix.
How is ear cytology stained?
Ears: Insert a cotton-tipped applicator into the vertical external ear canal. Then remove the applicator and roll it onto the slide. Heat fix the slide by applying flame to the back of the slide for a few seconds. Stain using the three-part Diff-Quik stain.
What is Diff-Quik fixative solution?
RAL Diff-Quik fixative solution It fixes air-dried blood smears. This methanol based solution will stabilize cellular components. Solution I and II are applied individually to the fixed smear to differentially stain specific cellular components.
What is true of Giemsa staining?
Giemsa stain is a gold standard staining technique that is used for both thin and thick smears to examine blood for malaria parasites, a routine check-up for other blood parasites and to morphologically differentiate the nuclear and cytoplasm of Erythrocytes, leucocytes and Platelets and parasites.
Which is the best Diff-Quick staining method?
The Diff-Quick staining method should be performed as follows: Greenish-Blue QuickLink III Fixative (Methanol): Dip the slide in the greenish-blue methanol fixative 20 times. Dark Orange QuickLink III Solution I (Sodium Azide): Dip the slide in the dark orange sodium azide solution 20 times.
How do you make a Diff Quik stain?
Diff-Quik stain The Diff-Quik stain consists of a fixative agent (methanol, blue), solution I (eosinophilic, orange) and solution II (basophilic, blue). Generally, slides are dipped sequentially into each solution 6 times (or left for 10-15 seconds in each solution), followed by a water rinse and drying.

Dip slide or tape-strip five times, for one second each, into Stain 2. Allow excess to drain after each dip. Rinse slide or tape-strip in distilled water or Weise’s buffer, pH 7.2.
