Zinc Salts What it replaces ** 1 Combo | Additive Coag Replaces Mercury precipitates (in alcohol) Corrosive (chloride better than sulfate) Zinc Formalin |
Zinc Formalin 4 Types w/ components and * | As is: LT IHC Storage, Fast Aqueous: ZSulf.Form.DI - precip in 70% Unbuffered Aq.: ZSulf.DI.Form - 6-8hr. fix Alcoholic: ZChlor.DI.Isopropyl.Form - antigens, nuclei, lipids |
Gluteraldehyde 2 alternatives w/PAS? Rate? use? | PBGTH + Form GTH NO - dialdehyde, false + Slow Penetration EM |
Alcohols 2 forms */* 2 Combos | Non-Additive Coag Ethyl - gout/urates | Methyl - Smears Carnoy + Clarke |
Carnoy Components, Use, Affect | Ethyl.Chloroform.Acetic Glycogen, DNA Shrinks within 4 hrs. |
Clarke Components | 100%.Acetic |
Acetone Speed/Temp 2 Actions | Non-Additive Coag Fast Refrigerated Fixes + Dehydrates |
Mercuric Chloride Use Frozen Sections? Pigment Color/Clearing 3 Combos | Additive Coag Mordant NO FROZEN SECTIONS Brown- Iodine + Na Thiosulfate B-5, Zenker, Helly |
B-5 Components, Use | Mercury Chlor.Na Acetate. Form Nuclear Detail |
Helly Stable or Unstable Use | Mercuric Chlor.Form.K Dichrom.Na Sulf.DI Unstable RBC Preservation |
Zenker Stable or Unstable Use | Mercuric Chlor.Acetic.K Dichrom.Na Sulfate.DI Stable Nuclear Detail |
Chromic Acid Use 2 Combos | Additive Coag Lipid Preservation Potassium Dichromate + Orth |
Potassium Dichromate When is it Coag Soft or Hard Wash Before... | With Acid (Otherwise Add NonCoag) Soft EtOH |
Orth Components, Use | K Dichromate. Na Sulfate. Form. DI Chromaffin in Cytoplasm |
Picric Acid Preserves... Wash With... 3 Combos | Additive Coag Glycogen 50% Before Processing Bouins, Gendre, Zamboni PAF |
Bouins Components, Use | Picric Acid.Acetic.Form Mordant for MT and Nuclear Detail |
Gendre Components, Use | Picric Acid.Acetic.Form.95% Glycogen Preservation |
Zamboni PAF Components, Use | PFA.Picric aq.Na Hydroxide.DI General use and EM |
Formalin PFA Difference? pH? Lipids? Pigment PEL/STEL | Add NonCoag No methanol - EM ok 7.5-8.0 Preserved before Processing Black Acid Hematin (Low pH) Remove: alc. PA and alkaline alc. 0.75ppm/2.0ppm |
