The key difference between Harris and Mayer’s haematoxylin is that Harris haematoxylin is used in regressive staining while Mayer’s haematoxylin is used in progressive staining. Haematoxylin is a basic dye that is commonly used in histopathology. It is a natural dye extracted from the tree Haematoxylon campechianum. It is a dark blue or purple colour […]
Difference Between Coating and Plating
The key difference between coating and plating is that coating can be done on both conductive and non-conductive surfaces, whereas plating can be done on conductive surfaces. Coating and plating are techniques used to cover surfaces of objects with a substance. We call this object the “substrate”. The purpose of this covering can be decorative, […]
Difference Between Catalase and Peroxidase
The key difference between catalase and peroxidase is that catalase catalyzes the decomposition of hydrogen peroxide into water and oxygen, whereas peroxidase catalyzes the decomposition of peroxides. Catalase and peroxidase are common enzymes. An enzyme is a biological component that is important in catalyzing chemical reactions by reducing the activation energy barrier of the reaction. […]
Difference Between Triethylamine and Triethanolamine
The key difference between triethylamine and triethanolamine is that triethylamine contains three ethyl group attached to the same nitrogen atom whereas triethanolamine contains three ethyl alcohol groups attached to the same nitrogen atom. The chemical compounds triethylamine and triethanolamine are organic compounds containing nitrogen atoms. These compounds have a nitrogen atom at the centre of […]
Difference Between Progressive and Regressive Staining
The key difference between progressive and regressive staining is that in progressive staining, the tissue is left in the staining solution just long enough to reach the desired endpoint while in regressive staining, the tissue is deliberately left for over staining until the dye saturates all tissue elements and then de-stained. Staining is a technique […]
Difference Between Calyx and Corolla
The key difference between calyx and corolla is that calyx is the collection of sepals while the corolla is the collection of petals of a flower. Flowers are the reproductive structures of flowering plants. They have several parts – petals, sepals, stamen, and carpel are the main parts. Each part performs distinct functions. Complete flowers […]
Difference Between Aliphatic and Aromatic Polyurethane
The key difference between aliphatic and aromatic polyurethane is that aliphatic polyurethane contains a chain structure whereas aromatic polyurethane contains a ring structure. Polyurethane or PUR is one of the largest class of polymers having properties that can be changed depending on applications. These materials can be either thermosetting or thermoplastic. Also, they can be […]
Difference Between Polycarbonate and Plexiglass
The key difference between polycarbonate and Plexiglass is that polycarbonate contains carbonate linkages as repeating units, whereas Plexiglass contains methyl methacrylate units as repeating units. Polycarbonate and Plexiglass are polymers. Polycarbonate is a synthetic resin in which the monomer units link with each other through carbonate linkages while Plexiglass is the trade name for polymethyl […]
Difference Between Nullisomy and Double Monosomy
The key difference between nullisomy and double monosomy is that nullisomy is the loss of both pairs of homologous chromosomes while double monosomy is the loss of one chromosome from each of two pairs of homologous chromosomes. Euploidy and aneuploidy are two chromosomal variations identified in organisms. Aneuploidy refers to a variation in the total […]
Difference Between Folded and Unfolded Protein
The key difference between folded and unfolded protein is that folded protein is a biologically active structure while unfolded protein is a biologically inactive structure. Translation produces a linear chain of amino acid sequence which does not possess a stable 3D structure. Therefore, amino acid sequences interact with each other and fold via a complex […]
