A group of 596 Staphylococcus aureus strains isolated from various clinical sources or implicated in food poisoning was investigated for enterotoxins A and B (SEA and SEB) production. The conventional ELISA techniques (competitive and sandwich ELISA) were compared with a newly developed avidin-biotin...
measures of quantity in a given brain region (morphological Aβ plaque loads, biochemically detected measures of Aβ levels (ELISA, western blotting)) [2, 3, 14, 41, 46, 50, 57, 59, 81], and 3. qualitative changes in the composition of detectable modified and non-modified Aβ species...
Moreover, a threshold-based evaluation of CSF p-tau, as for other fluid biomarkers, can have limitations tied to the risk of false negative results, whose occurrence also encompasses pre-analytical (e.g., collection techniques, handling of samples, storage conditions) and analytical variables (e...
In this study, 24 randomly selected cows of the Fresian breed from a dairy herd with a history of Ptbc were used to evaluate the performance of different diagnostic techniques. These animals did not show clinical signs of the disease. However, another animal from this herd presented evidence ...
the discrepancy with the value reported in Table 1 is attributed to the fact that they were obtained through different techniques, as previously observed (28). Binding of Gal-4FL to a bacterial LPS composed by a H type-1 antigen analogue LPS are composed of three structural elements: the hy...
Determination of antibody titer using ELISA, HI and VNT techniques. Finally, enumeration of aerobic bacterial count for living attenuated Bacterial vaccine by culture technique. Homogeneity and stability results for all vaccines were accepted criteria according to TS/ISO 22117...
By employing this method alongside newer or alternative techniques, it provides a reference or benchmark. This can help validate the results from other methods, ensuring accuracy and reliability. While the carbazole method has its drawbacks in terms of the time and effort required, its benefits in...
The aim of the present study is thus to investigate the biological role of hypoxia-induced ANGPTL4 in SGC progression. We determined that ANGPTL4 expression was specifically induced by hypoxia in SGC cell lines, and we used siRNA knockdown (KD) techniques to evaluate the role of ANGPTL4 in ...

autoimmune antibodies against the biomarkers chosen from the above-mentioned group indicates the occurrence of non-small cell lung carcinoma in patients providing the serum samples. An example of techniques that can be used to detect the presence of autoimmune antibodies is 1D- and 2D-western blot....
