John Kiernan's Files

Files containing directly available information (text, tables, pictures) will be opened and displayed if you click on the link, just as you do for every other web site. Save such files to your own computer if you want to keep them. Graphics files will be opened with the program (app) that you usually use. 

My favourite viewer for photos and other pictures is IrfanView. For simple editing, such as adding lines and labels to pictures, or concealing blemishes, the Paint program that comes with Windows 10 is, in my opinion a great improvement on its predecessors. Windows Paint has always been easier to use than PhotoShop.    

Files with names of the form filename.zip are archives. When you click on a link to an archive you will be invited to download the file. Each archive contains several compressed files. To use a .ZIP archive you must download it and then decompress it.  Recent versions of Windows (7, 10) include WINZIP and WINRAR, which do this well.  PDF (portable document format) files require the Adobe Acrobat Reader. If you don't have this free program, click here to download it.  Other free PDF readers include Foxit Phantom (Foxit Phantom) and SodaPDF (Soda PDF), both of which can also be used to create and edit PDF files.  



The files fall into three groups:

Histochemistry etc.

My research, from the 1960s to the 2010s, involved using histotechnology.

1. Utilities for chemical calculations:
  • Molecular weight of an entered formula
  • Molecular weight and isoelectric pH of an entered peptide sequence
  • Interconversion of concentrations (molar, gm/100ml etc) based on molecular formula

2. Practical instructions with explanations

  • Fixatives
  • Protective film for slides
  • Stains
  • Mounting media
  • Frequently asked questions

3. Links to other web sites

  • Biological stains
  • Histochemistry
  • Histology
  • Immunohistochemistry
  • Microtechnique

  • Pictures: Structure of the nervous system in a wide range of animals
  • Notes and lecture handouts
  • Slide shows for selected topics
  • Annotated drawings: Neuroanatomy and diseases of the brain and spinal cord
  • Interactive tutorial program: Development and adult anatomy of the human nervous system and special sense organs
  • Multiple choice questions: Human neuroanatomy
  • Short-answer questions: General, human and comparative neuroanatomy
  • Glossary: Look up neuro-words, including eponyms
  • Basic functional neuroanatomy: A 35-page summary of the subject.

Command line utilities.  These are for older people who still like to use DOS commands and batch files. They were written and compiled in the 1990s with ASIC (Version 5), a dialect of BASIC that generates small, efficient .COM or .EXE files.  Each utility comes with an explanatory plain text file.  Most also have built-in help.  They work with the Windows Command Prompt (C:\_) but JPsoft's free Take Command alternative program is easier to use; their Version 9 is adequate, but they have many more recent versions for enthusiasts. 

To use these in 64-bit Windows (as on most laptops) it is necessary to install DOSBox, a free (public domain) emulation program.  Click here for the latest version of DOSBox

Histochemistry and histotechnology files

Utilities for chemical calculations.  These include three command-line programs that calculate data about entered chemical formulae. For example, if you enter:   MW NaHCO3  the formula and molecular weight of sodium bicarbonate will appear on the screen as  NaHCO3  84.00687.  This result can be sent to a comma-delimited database file if desired.
   With the solutions utility you could type
  SOLUTION  H2NCONH2  6.5M  and obtain the concentration of 6.5M urea in various units, including 39.04 grams per 100 ml. You can also use SOLUTION to obtain molarity from grams per litre or percent w/v.
   For a peptide sequence,
  PEP  gly-lys-trp-arg   tells you that this tetrapeptide has molecular weight 545.67 and that its pI is approximately 8.7.
You will need to install the DOSBox emulation utility (free download) to run these utilities on a computer with 64-bit versions of Windows (Most laptops).  They still (Jan 2024) work well with 32-bit Windows 10, with no need for a DOS emulation utility.

FAQ: Staining, histochemistry and histotechnology.  An indexed collection of frequently asked questions on 84 topics, grouped in 6 major categories. Some topics include more than one question and answer. Many are documented with references to books and other publications. Several people have contributed answers, many of which have appeared on the Histonet listserver. This FAQ is a single quite large file (220 KB) so it may take a minute or two to load by way of a slow internet connection. Once loaded, movement among its links is instantaneous. This FAQ is updated from time to time. Consult the FAQ
Glossary of Staining Methods, Reagents, Immunostaining, Terminology and Eponyms. This is the largest online compilation of definitions in the field of histotechnology, maintained by the Biological Stain Commission on their website and updated from time to time by RW Dapson, RW Horobin and JA Kiernan.   Consult the BSC's  Glossary
Keeping sections on slides.  A review of the approaches to this old problem: positively charged slides (APES, polylysine); adhesives (especially chrome gelatin); and other tricks too. Read about adhesives for keeping sections on slides.
Coating slides with nitrocellulose (= celloidin or collodion).  Detailed instructions for encasing slides in nitrocellulose film to prevent removal of sections by harsh liquids such as alkalis and hot acids. Includes references. Read how to treat slides with nitrocellulose.
Making your own aqueous mounting media.  Instructions for making aqueous mountants. Why buy, when it's cheap and easy to make your own? Originally published in Microscopy Today, and reproduced with permission. Recipes and instructions for 4 aqueous mountants.
Formaldehyde, paraformaldehyde and glutaraldehyde.  What they are and what they do. A short review of how aldehyde fixatives work, with chemical schematics and references.  Originally published in Microscopy Today, and reproduced with permission. Read about formaldehyde and glutaraldehyde.
How to stain motor end plates.  A brief overview, with references, of combined techniques for acetylcholinesterase activity and the terminal branches of motor axons in skeletal muscle.  Originally published in Microscopy Today, and reproduced with permission. Read about staining neuromuscular innervation.
Formaldehyde fixation and immunohistochemistry. An article that appeared in an NSH regional newsletter in 2005, explaining the actions of formaldehyde and why this fixative often impairs subsequent application of immunohistochemical methods. (PDF file)  Read about actions of formaldehyde on antigens
Antigen retrieval. Another article that appeared in an NSH regional newsletter in 2005, discussing procedures for unmasking antigens in sections of formaldehyde-fixed tissue. The possible mechanisms of several antigen retrieval procedures are discussed. (PDF file) Read about antigen retrieval
