An immunoperoxidase assay for the detection of African horse sickness virus (AHSV) in formalin-fixed tissues is a valuable tool in the study of the pathogenesis of the disease, as well as a useful addition to existing diagnostic tests when only preserved tissues are available. An assay that uses Hamblin antiserum in a basic avidin-biotin complex detection system was standardized and validated i...
INTRODUCTION Conventional formalin-fixed, paraffin-embedded tissue provides superior cellular morphology and long-term storage. Problems with formalin fixation comprise delay of fixation and variations in the duration of fixation. Microwave assisted tissue fixation removes the use of noxious and potentially toxic formalin that decreases the turnaround time and creates a personnel friendly workf...
Fine needle aspiration (FNA) is a rapid tool for detection of breast carcinomas. Evaluation of estrogen and progesterone receptors (ER, PR) and HER2 expression by immunohistochemistry (IHC) are routinely performed in breast carcinomas. Formalin fixation of tissue for a minimum of 6 hours, and for HER2 not more than 48 hours is the current recommended practice. In this retrospective study, we co...
Toxicological analyses of medicines and chemicals in formaldehyde-treated specimens are a component of forensic toxicology. This review involves two parts: (i) reactions of formaldehyde with substances in tissues fixed with formalin (aqueous formaldehyde solution) and (ii) the stability of substances in formalin-treated tissues and formalin solutions. Because it was well known that formaldehyde...
The occurrence of RNA in plastids from etiolated and green maize leaves was demonstrated cytochemically, with both the light and the electron microscope. Etiolated leaves were allowed to incorporate tritiated cytidine for several hours and were subsequently fixed in formalin. Radioautographs of leaf sections 2 micro thick showed silver grains over the regions of the cytoplasm containing plastid...
