domanda abbastanza semplice, ma guardando in giro non sono riuscita a trovare un gran che: la colorazione Diff-Quick ( è la stessa cosa dell'emacolor??) serve per il sangue..ma cosa esattamente va a colorare??qlc tipo cellulare specifico?? e che tipo di colorazione è? nel senso non è una marcatura con anticorpo immagino..mmm....chiaritemi le idee!!
da quel che ho trovato colora leucociti in modo diverso ma li colora tutti e non è specifico, non usa anticorpi ma la colorazione dipende dal precipitato formato dall'aggiunte di soluzioni acquose a blu di metilene e eosina. ho trovato il protocollo su http://www.ihcworld.com/_protocols/special_stains/diff_quick_ellis.htm Method Paraffin Sections
1. Bring sections to distilled water 2. Stain with “Diff Quick” solution II .30 secs 3. Counterstain (optional) with “Diff Quick” solution I for 30 seconds 4. Rinse rapidly in tap water 5. Rapidly dehydrate in absolute alcohol (exposure to alcohol should be as brief as possible to prevent excessive decolourisation) 6. Clear and mount
Smears/Imprints
1. Air-dry the smear 2. Fix in “Diff Quick” Fixative (or methanol) for 30 secs/drain 3. Stain with “Diff Quick” solution II for 30 secs/drain 4. Counterstain (optional) with “Diff Quick” solution I for 30 secs/drain 5. Rinse in tap water to remove excess stain 6. Rapidly dehydrate in absolute alcohol 7. Clear and mount
