I am analyzing of imgae j software
but when i will try to adjust thershold level haematoxycillin stain is interfereing with DAB (following according to method mentioned on http://rsb.info.nih.gov/ij/docs/examples/stained-sections/index.html i.e. Quantifying Stained Liver Tissue) How can i quantity only leaving out Haematoxycillin ? its urgent plz regards santosh |

You can separate the stains that way, but I you must be aware that DAB staining cannot be quantified reliably by its intensity. This has been raised several times here already.

Thank you for your reply
according to mailing list archive: DAB cannot be used for absorption photometry, as it does not meet the Beer-Lambert criteria for a phometric material. (http://n2.nabble.com/Re--Nuclear-volume,-ploidy-and-Stain-stochiometry-td2347676.html) But I feel Color Deconvolution plugin it is at least differentiating colours. I have seen some articles in which they have used for quantitative immunohistochemistry for DAB stained slides softwares like Image pro plus and Q-IHC. So What is the best solution available for quantitative immunohistochemistry for DAB stained slides?

Degree of DAB darkness is not indicative of expression of the antigen one is detecting, which is why people do the 'quantification'. Yes, some papers might have gone through the reviewing process, but you do not know how many have been rejected by knowledgeable reviewers. Cheers G |

Dear Santosh,
As G. Landini and Al Floyd mentioned, DAB is not in rigor a truly absorptive material and you might have trouble publishing your data if your method uses densitometry quantification based on the law of Lambert-Beer. It is very common, not withstanding, to find in situ hybridization quantification of brains slices dipped into autoradiographic emulsions. Silver granules, which likewise, do not satisfy Lambert-Beer criteria, is quantified by densitometry in darkfield microscopy where light is reflected!(A quick pubmed search will reveal) Now, I don't want to justify an error with another one, the question is whether there are more white pixels created by reflective silver spots where there are molecules of interest. The rule that DAB can not be used at all might not be a general rule and be more like a rule of thumb as this can vary from antibody to antibody according to Watannabe et al(See below). In case positive, although one can not estimate the true number of molecules in situ on the basis of Lambert-Beer law, one would in principle be able to compare rough relative amounts (e.g. a semi-quantitative estimate of the proportion of molecules) in this tissue site as opposed to another tissue site subjected to the same conditions by photometric densitometry (granted exposure to the same solutions, for the same amount of time, same illumination settings, lab temperature, etc). A couple of works have addressed this question. In the case of DAB deposited by a antibody-biotin, avidin-peroxidase mesh, I recommend you read this work: HUANG, X.; CHEN, S.; TIETZ, E. I. Immunocytochemical detection of regional protein changes in rat brain sections using computer-assisted image analysis. The Journal of Histochemistry and Cytochemistry: Official Journal of the Histochemistry Society, v. 44, n. 9, p. 981–7, set. 1996. ISSN 0022-1554. PMID: 8773563. And this WATANABE, J.; ASAKA, Y.; KANAMURA, S. Relationship between immunostaining intensity and antigen content in sections. The Journal of Histochemistry and Cytochemistry: Official Journal of the Histochemistry Society, v. 44, n. 12, p. 1451–8, dez. 1996. ISSN 0022-1554. PMID: 8985137. For a more in-depth description of the main sources of variation in Imunohistochemistry I recommend this: TAYLOR, C. R.; LEVENSON, R. M. Quantification of immunohistochemistry– issues concerning methods, utility and semiquantitative assessment II. Histopathology, v. 49, n. 4, p. 411–24, out. 2006. ISSN 0309-0167. PMID: 16978205. And finally, to avoid uninformed mistakes: ROSSNER, M.; YAMADA, K. M. What’s in a picture? the temptation of image manipulation. The Journal of Cell Biology, v. 166, n. 1, p. 11–5, jul. 2004. ISSN 0021-9525. PMID: 15240566.
