Introduction Whoever thought that the small fly hovering over fruits will become such an essential asset for genetics research!! Fruit flies are one of the first extensively used model organisms in labs. Moreover, it is one of the first model organisms which was brought ‘from nature to labs’ to understand the genetics of the organisms! […]
Need Electrophoresis Equipment for your research? Click here Cellulose acetate electrophoresis is a type of zone electrophoresis that separates molecules in liquid form such as proteins on a membrane or stripe made of cellulose acetate. Developed by a German chemist, Joachim Kohn (1912-1987) in 1957, cellulose acetate electrophoresis was the second form of zone electrophoresis, […]

Over 1.5 million species of fungus have been discovered and they are found in a range of habitats. Some characteristic […]
Reference to this article: ConductScience, Estimating the Chiasma Frequency in Diplotene-Diakinesis Stage (2019). doi.org/10.55157/CS20200925 Introduction Chiasma is the point of crossing over or site where the exchange of genetic material takes place between two homologous, non-sister chromatids. The crossover occurs in the pachytene stage, however, it is observed in the diplotene stage of meiosis-I[2]. The […]
Agarose gel electrophoresis is a type of gel electrophoresis that uses agarose, a natural polysaccharide isolated from red seaweed agar, as a matrix to separate molecules or components based on their size. It is an uncomplicated, yet versatile analytical method that can accommodate both research and routine laboratory works. It is nowadays considered a conventional […]
Need Electrophoresis Equipment for your research? Click here Gel electrophoresis is a type of electrophoresis that separates molecules or components based on their size or conformation in a matrix made from gel-forming substances. Since its conception, gel electrophoresis has been modified, in terms of gel types, composition, and the set-up of the system to accommodate […]
Need Electrophoresis Equipment for your research? Click here Electrophoresis is a technique that separates molecules in their liquid state, based on their ability to move in an electric field. The various forms and types of electrophoresis have become the leading methods of the analysis of biomolecules in biochemistry and molecular biology, including genetic materials […]
Need Microtomes for your studies? Click here As an Amazon Associate, ConductScience Inc. earns revenue from qualifying purchases What is the Ultramicrotome? Microtomes are specifically designed devices for the cutting of extremely thin sections from samples, for the study of their microscopic composition. Samples can be of biological origins, such as tissues, cells, and […]
Introduction Since the discovery of chromosomes, the cytogenetic field has evolved rapidly. The techniques have unfolded several hidden mysteries of chromosomes. And later, it gave rise to two branches: molecular and clinical cytogenetics. The studies in clinical cytogenetics suggested that the structural and numerical aberrations of chromosomes (autosomal and sex) are the cause of […]
As we know, cytogenetics is the study of chromosomal structure and behavior by using different staining techniques. In the year 1962, Lejeune proved Waardenburg’s hypothesis (the cause of Down syndrome could be a chromosomal aberration) by reporting the first case of syndrome due to chromosomal aberrations. It was a major breakthrough in cytogenetics research.[2] With […]
As an Amazon Associate, ConductScience Inc. earns revenue from qualifying purchases Introduction Histology is a routine lab technique used to evaluate the morphology and structure of cells, tissues, and organs under the microscope. Histological studies of biological samples often lead to the establishment of structure/function relationships, which may have diagnostic and prognostic value in the […]
As an Amazon Associate, ConductScience Inc. earns revenue from qualifying purchases Introduction Cytogenetics is the study of the structural and functional properties of the chromosome. It includes chromosomal structure, function, behavior – during mitosis and meiosis, and influence on the phenotype of an organism. It is used as a tool to understand genetic phenomena due […]
