Immunohistochemistical detection of Tau antibody [E178] (ab32057) on formaldehyde fixed paraffin-embedded rat tongue sectionsAntigen retrieval step: Heat mediated. Buffer Used: Citric acid pH6. Permeabilization: None. Primary antibody incubated at 1/1000 for 2 hours @ 21°C in TBS/BSA/azide. Secondary antibody: anti Rabbit IgG Conjugated to Biotin (1/200). A strong pattern of immunostaining which appears to be mostly localised to nerve fibres and their cell bodies (Islet of Langerhans cells are also positive). In submitted image of central area of tongue coloured arrowheads indicate features: red for nerves cut in cross-section (T/S), each brown dot representing a single axon green for what appears to me to be small nerve fibres wrapping around a partial muscle fibre black for a Ganglion containing seven positive nerve cell bodies. Surrounding these are collagen fibres (C), adipocytes (A) and skeletal/striated muscle fibres in L/S ( M- showing blue myocyte nuclei arranged around the periphery of each fibre).
Immunohistochemistical detection of Tau antibody [E178] (ab32057) on formaldehyde-fixed paraffin-embedded human salivary gland sections. Antigen retrieval step: Heat mediated. Buffer Used: Citric acid pH6. Permeabilization: No. Blocking step: 1% BSA for 10 mins @ 21°C. ab32057 incubated at 1/1000 for 2 hours @ 21°C in TBS/BSA/azide. Secondary antibody: anti rabbit IgG conjugated to Biotin (1/200). NB: An interesting pattern of positivity that seems to be supported by the Human Protein Atlas. Coloured arrowheads in the submitted image indicate features: red for positive serous glands, blue for positive intra-lobular collecting ducts, black for negative mucous glands (there is a serous demilune around this acinus), yellow for intralobular collecting ducts, green for nerve tracks in the interlobular areas, blue for positive interlobular collecting ducts. There appears to be a population of positive nuclei but this may be due to the fact that ab32057 @ 1/1000 gives a positivity that is too strong (should be further diluted).
