The collection contains research documentation of Dr Peter Wooding relating to his work on the comparative study of cell structure and function of ruminant mammary glands and placentas using light and electron microscopes and immunocytochemical techniques. This was carried out at the Babraham Institute near Cambridge and later at the Physiology Dept Cambridge University. The largest series are sample books describing the source and preparation of cell samples in three numerical sequences: 34 – 999 followed by a second series 1-999 and finally a third N1-N286. There is one observations record book [there were several] from the C-100 electron microscope detailing photographs taken by Wooding [stored in a separate numerical sequence] of the numerically identified cell samples. Two card files contain records of antibody samples obtained from other researchers and commercial sources. There is a series of notebooks documenting Wooding’s daily observations of individual antibody localisations [on samples identified by reference back to the original numbered samples] using light microscopy. There is also one notebook containing references to papers relevant to Peter Wooding’s research.
