Numerous types have been designed to check the interactions of tissue fixation and immunorecognition, but most have seen the situation in immunorecognition as staying absolutely due to fixation.
He continues to be a member with the college of UAB considering that 1981 and presently is Professor of Pathology and Head of This system in Translational Research in Neoplasia. His research interests largely are in using biomarkers in scientific medication and research on factors for instance tissue processing and fixation that impact the usage of biomarkers in early detection, determining prognosis, predicting efficiency of therapies in risk evaluation and as surrogate close points for assessing novel therapies for instance gene therapy.
Dr. Atha and colleagues discovered that commercially promoted antibodies to an antigen had been quite variable Bright field imaging as for their actual targets (Jakupciak et al. in press).
