Synthetic peptide conjugated to KLH derived from within residues 50 - 150 of Human PON2.
(Peptide available as ab41542.)
Our Abpromise guarantee covers the use of ab40969 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 40 kDa (predicted molecular weight: 40 kDa).Can be blocked with Human PON2 peptide (ab41542).|
|ICC/IF||Use a concentration of 5 µg/ml.|
Immunohistochemistical detection of PON2 antibody (ab40969) on formaldehyde fixed paraffin-embedded mosue kidney and lung sectionsAntigen retrieval step: Heat mediated. Buffer: Citric acid pH6. Permeabilization: None. Blocking step: 1% BSA for 10 mins @ 21°C. Primary antibody incubated at 1/2000 for 2 hours @ 21°C in TBS/BSA/azide. Secondary antibody: anti Rabbit IgG Conjugated to Biotin (1/200). Patterns of immunostaining are produced that appear to be very similar to those seen on the HPA website, for these tissues. In the submitted composite image, both tissues show intense labelling. In the upper image of kidney cortico-medullary junction, apical membrane positivity is observed in proximal/distal tubules. In the same tubules globular intra-cytoplasmic positivity is also observed. In the lower image of lung, positivity is evident in the simple columnar epithelium of the bronchioles and also in what appear to be alveolar macrophages. This antibody should be diluted further, under the conditions used.
