MICRO 290 Lab Practicum
Acid Fast Staining substances wished - ANS-Primary stain- carbolfuchsin, decolorizer-acid
alcohol, counterstain-methylene blue.
DH2O to rinse
Bunsen burner
Slide
Acid Fast Staining method - ANS-1. Add a drop of albumin to surface of slide and a drop of the
blended way of life. Air dry, heat repair (best pass via flame two times)
2. Obtain plastic dish and lid. Place layers of paper towel and moisten them (removing excess
moisture).
Three. Place warmth constant smears atop the moist paper towels. Cover smears with 2 strips
of paper towel, then flood surface of strips with carbolfuchsin.
4. Snap lid in vicinity, leaving one part open for venting. Place box in microwave and warmth for
1 minute at 100% power.
5. Remove box from microwave, dispose of slides from field, region on staining rack.
6. Apply decolorizer with the aid of tilting slide at 45 degree perspective. Allow acid-alcohol to
run across smear for 15 seconds.
7. Rinse with dH2O.
Eight. Apply methylene blue counter stain via flooding surface of smear and allowing to sit down
1 minute.
Nine. Rinse with dH2O, blot dry.
Acid Fast Staining motive - ANS-•Important diagnostic stain
•Differentiates acid-fast micro organism (pink) from non-acid-speedy micro organism (blue)
•Important in clinical microbiology
•Mycobacterium
-Tests to pick out mycolic acid
Aseptic Technique through Direct Flame Method - ANS-Turn on bunsen burner then place loop
in flame for sterilization functions and to make certain there may be no contamination
Capsule staining technique - ANS-DO NOT HEAT FIX
1. Place a single drop if India ink on a clean microscope slide, adjoining to the frosted edge.
2. Using a flamed loop and sterile method do away with organism you will use and blend with
India ink. Be sure there are not any clumps and do not spread drop
three. Place the give up of some other easy microscope slide at an attitude to the cease of the
slide containing the organism. Spread out the drop into a film. This is completed by contacting
