SUGGESTED STAINING PROTOCOL
A. PRELIMINARY PREPARATION
For Paraffin-Embedded Tissues
1. Fix target tissue in 10% NBF (Neutral Buffered Formalin), or in an alcohol-based fixative (such as alcohol or Methacarn). Process tissues for paraffin embedding.
2. Cut tissue 3-4 microns and place on Zymed’s HistoGrip™ (Cat. No. 00-8050) or poly-L-lysine coated slides. Dry slides in a 60°C oven for 1-2 hours.
3. Deparaffinize slides in 2 changes of xylene for 5 minutes each. Rehydrate slides in a series of graded alcohol.
4. (Optional): Block for endogenous peroxidase activity with 3% H2O2 in methanol for 10 minutes. Rinse slides in 3 changes of PBS for 2 minutes each.
5. Slides are now ready for PCNA staining.
6. (Optional): Specific staining of formalin-fixed, paraffin-embedded tissues may be enhanced using a Heat Induced Epitope Retrieval (HIER) method.
7. (Optional): If alcohol-fixed tissues are used, tissue sections can be post-dipped in 10% NBF for 30-60 seconds. Rinse well. This may improve morphology.
For Cultured Cells and Cell Suspensions
1. Fix cells in 70% alcohol or acid-ethanol for 15-20 minutes at 4°C. Acetone or Methacarn fixatives can also be used.
2. If necessary, block for endogenous peroxidase activity with 3% H2O2 in methanol for 10 minutes.
3. Wash in 3 changes of PBS for 2 minutes each.

PROTOCOLLO DI COLORAZIONE SUGGERITO
A. PREPARAZIONE PRELIMINARE
Per tessuti inclusi in paraffina
1. Fissare il tessuto bersaglio in 10% NBF (Formalina Neutra Tamponata), o in un fissante a base di alcool (come alcool oppure Methacarn). Preparare i tessuti per l’inclusione in paraffina.
2. Tagliare i tessuti 3-4 micron e porli su Zymed’s HistoGrip™ (Cat. No. 00-8050) oppure vetrini rivestiti di poly-L-lysine . Far asciugare i vetrini in forno a 60°C per 1-2 ore.
3. Sparaffinizzare i vetrini in 2 cambi di xilene per 5 minuti ciascuno. Reidratare i vetrini in una scala crescente di alcool .
4. (Facoltativo): Bloccare per perossidasi endogena con 3% H2O2 in metanolo per 10 minuti. Risciacquare i vetrini con 3 cambi di PBS per 2 minuti ciascuno.
5. I vetrini sono ora pronti per la colorazione PCNA.
6. (Facoltativo): Colorazione specifica di tessuti fissati in formalina, inclusi in paraffina può essere evidenziata utilizzando un metodo Recupero di Epitopi mediante calore (Heat Induced Epitope Retrieval) (HIER).
7. (Facoltativo): Se si utilizzano tessuti fissati in alcool, le sezioni di tessuto si possono immergere poi in 10% di NBF per 30-60 secondi. Risciacquare bene. Questo potrebbe migliorare la morfologia.
Per Cellule Coltivate e Sospensioni cellulari
1. Fissare le cellule in 70% di alcool oppure acido-etanolo per 15-20 minuti a 4°C. Si possono utilizzare acetone oppure fissativi Methacarn.
2. Se necessario, bloccare per la perossidasi endogena con 3% H2O2 in metanolo per 10 minuti.
3. Lavare in 3 cambi di PBS per 2 minuti ciascuno.
