This review focuses on the potential of immunoscintigraphy with radiolabeled monoclonal antibodies in patients with pancreatic cancer. The general limitations of tumor immunoscintigraphy are particularly important in the case of pancreatic cancer, because of the particular anatomic location, that is in close proximity with sites of physiologic high accumulation of radioactivity during such exam...

background: bradford protein assay is popular due to its ease of performance and relative sensitivity. many researchers and laboratories in iran use standard assay of bradford by cuvette. no commercial kit was available for bradford microplate assay in iran. meanwhile, imported bradford commercial kits are very expensive and have a long delivery time in iran. till now no study or document on br...

It is generally recognized that the most useful and convenient means of quantitatively determining members of the vitamin B complex involve microbiological methods. Several methods of this type have been proposed for the assay of thiamine but each one in use today possesses certain inherent disadvantages that limit its value. The fermentation method of Schultz, Atkin, and Frey (1,2), based on t...

In assaying for sulfatases it is possible to use several methods which have been devised for the determination of inorganic sulfate. As a test for chondrosulfatase, the micro benzidine method developed by Dodgson and Spencer (1) is usually employed. This method appears to be the most suitable because of its good sensitivity and absence of substrate interference, but its technique is complicated...

streptococcus agalactiae is acommensalorganism, but it may cause infection in susceptible hosts. the aim of this study was to evaluate pcr assay compared with conventional culture method for direct detection of streptococcus agalactiae . total of 203 paired low vaginal swabs were collected from women at 35-37 weeks of pregnancy from june 2013 through february 2014 for detection of streptococcus...

Pigmentation is induced by production of melanin in specialized organelles termed melanosomes and by transfer of these organelles from melanocytes to surrounding keratinocytes. The chemical basis of melanogenesis is relatively well known but the mechanism of melanosome transfer is not well studied. Various pigmentary disorders and cosmetic applications require the use of depigmenting agents. Cu...

A simple, rapid assay for cephalosporins is described. The method is based on the inhibition by cephalosporins of the fermentation of glucose or inositol by a strain of Providence resistant to aminoglycoside antibiotics. The method gives answers which are as accurate as those obtained by standard agar diffusion techniques within four hours, and utilizes skills and resources readily available in...

Commercially available analytical kits for the estimation of total antioxidant status are expensive and time-consuming. Most of the commercially available kits for total antioxidants estimation are based on the principle of suppression of ABTS radical cation formation by antioxidant in the serum sample. The method requires stringent assay conditions, like exact incubation time and the temperatu...
