Study Notes
Staines e su usos
- Hematoxylin e Eosin (H&E): Un stain general usate in histologia pro colorar nucleos (hematoxylin, color blau) e cytoplasma (eosin, color rosate).
- Gram Stain: Differentiate le parietes cellular de bacterias in duo gruppo: gram-positive (color purpur) e gram-negative (color rose).
- Ziehl-Neelsen Stain: Detecta bacterias acido-resistente, como Mycobacterium tuberculosis (color rubie).
- Giemsa Stain: Examination de cellulas sanguinee e detection de parasitos; colorate cellulas sanguinee e parasitos (p.ex., Plasmodium in malaria).
- Periodic Acid-Schiff (PAS) Stain: Detecta glycogen e mucopolysaccharidos; colorate glycogen e altere carbohydratos (color magenta).
- Wright's Stain: Examination de smears de sanguine; differentia le typos de cellulas sanguinee.
- Silver Stain: Visualisation de fibras reticulares e fungos; colorate fibras reticulares, certe bacterias e fungos.
- Trichrome Stain: Differentia musculo, collageno e cytoplasma; colorate fibras muscular (color rubie), collageno (color blau/verde) e cytoplasma (color rose).
- Sudan Stain: Colorate lipidos; colorate lipidos (color orange o nigre dependente del typo).
- Alcian Blue: Colorate mucopolysaccharidos acide; colorate mucopolysaccharidos acide (color blau).
- India Ink: Visualisation de capsulas in microorganismos; colorate capsulas, particularmente in Cryptococcus neoformans.
- Congo Red: Detection de amyloide in tissus; colorate depositos de amyloide (color rubie sub le microscopio optic; birefringentia verde-pomme sub lumine polarisate).
Reagentes e su usos
- Benedict's Reagent: Detection de sucres reductante; cambia color de blau a orange/rubie in presentia de sucres reductante.
- Biuret Reagent: Detection de proteines; diventa violette in presentia de ligationes peptidic in proteines.
- Fehling's Solution: Detecta sucres reductante, specialmente in carbohydratos; cambia de blau a un precipitate rubie-brique si le sucres reductante es presente.
- Gram's Iodine: Usate in le coloration de Gram pro bacterias; agisce como un mordante pro fixar le stain de violetto de crystall in bacterias gram-positive.
- Sodium Hydroxide (NaOH): Regulation del pH; reactiones de neutralisation; un base forte communmente usate in titrationes e pro ajustar le pH.
- Hydrochloric Acid (HCl): Regulation del pH; usate in le digestion de specimens biologic; un acido forte usate in titrationes e pro dissolver specimens.
- Ethanol: Usate in le purification de ADN/ARN e le coloration de Gram; precipita ADN/ARN e decolorise in le coloration de Gram.
- Formalin: Fixation de tissus in histologia; conserva le tissus per ligação de proteines.
- Methanol: Fixation in smears sanguinee e ADN; fixa cellulas e precipita acidonucleic.
- Phenolphthalein: Indicator del pH in titrationes acido-base; deveni rose in solutiones basic.
- Acetone: Usate como un agente de deshydratation e solvente; communmente usate in histologia pro deshydratation.
- Silver Nitrate: Coloration in histologia e microbiologia; colorate bacterias e fungos; etiam usate in cura de plagas como un antiseptic.
- Sodium Chloride (NaCl): Mantene le equilibro osmotic in cellulas e specimens de tissus; communmente usate in tampones physiologic.
- Ammonium Sulfate: Precipitation de proteines; precipita proteines per "salting out".
- Tris Buffer: Stabilisa le pH in solutiones biologic; un tampon commun pro mantener le pH.
- Giemsa Stain: Colorate cellulas sanguinee e parasitos; usate in hematologia pro differentiar le typos de cellulas.
- Acetic Acid: Usate in le extraction de ADN e le regulation del pH; aiuta in le precipitation de acidonucleic.
Typos de cultures e su usos
- Nutrient Agar: Medium general-proposito pro bacterias non-fastidiose; supporta un ample gamma de crescentia bacterial.
- Blood Agar: Detecta le activitate hemolytic de bacterias; arricchite con sanguine de oves o human; monstra patrones de hemolyse (alpha, beta, gamma).
- Chocolate Agar: Cresce organismos fastidiose como Haemophilus e Neisseria; agar sanguinee calefacite; libera factores de crescentia como NAD e hemin.
- MacConkey Agar: Selective pro bacterias Gram-negative; differencia fermentatores de lactose; contine sales de bile e violetto de crystall; fermentatores de lactose deveni rose.
- Mannitol Salt Agar (MSA): Selective pro species de Staphylococcus; differencia fermentatores de mannitol; alte concentration de sal; fermentatores de mannitol deveni jalne.
- Thayer-Martin Agar: Isolation de Neisseria gonorrhoeae e Neisseria meningitidis; contine antibioticos pro inhibir le flora normal.
- Sabouraud Dextrose Agar: Cultura de fungos, specialmente levuras e moldes; pH acide e alte concentration de zucchero inhibi le crescentia bacterial.
- Cetrimide Agar: Selective pro Pseudomonas aeruginosa; contine cetrimide, que inhibi altere bacterias.
- Buffered Charcoal Yeast Extract (BCYE): Cultures Legionella species; arricchite con carbon pro detoxificar productes de decomposition que inhibi le crescentia.
- Xylose Lysine Deoxycholate (XLD) Agar: Selective pro Salmonella e Shigella; Salmonella appare con centros nigre; colonias de Shigella es transparente.
- Lowenstein-Jensen Medium: Isolation de Mycobacterium tuberculosis; contine verde de malachite pro inhibir altere bacterias.
- Campy-BAP (Campylobacter Blood Agar): Isolation de species de Campylobacter; arricchite con antibioticos pro inhibir le flora intestinal normal.
- Thioglycolate Broth: Cultivation de bacterias anaerobic; agentes reductante crea un gradiential de oxygeno pro anaerobes al fundo.
