Microscopy Types and Techniques

Fluorescence Microscopy: Utilizes fluorescent molecules to label and visualize specific proteins or cellular structures.
Resoluble Distance Formula: The resolvable distance between two objects is calculated using the formula: Resolving Power = λ / (2NA), where λ is the wavelength of light and NA is the numerical aperture of the lens.
Transmission Electron Microscopy (TEM): Employs a beam of electrons to generate high-resolution images of thin samples, allowing detailed visualization of structures.
Live Cell Imaging: Techniques such as Fluorescence or Phase Contrast Microscopy are used to visualize live cells and tissues in real-time, capturing dynamic processes.
Secondary Antibody in Immunofluorescence: Binds specifically to the primary antibody and is conjugated with a fluorescent dye, amplifying the signal for better visualization of target proteins.
Scanning Electron Microscopy (SEM): Used to examine the surface structure of cells and tissues, providing three-dimensional images.
Light Microscopy: Generally used to visualize internal structures, relying on various staining methods to highlight cellular components.
Dichroic Filter Function: In fluorescence microscopy, it reflects specific wavelengths of light while allowing others to pass through, enabling selective excitation of fluorescent dyes.
Primary Function of Confocal Microscopy: Enhances optical resolution and contrast by using a spatial pinhole to eliminate out-of-focus light, allowing precise depth imaging of samples.

Protein Structure

Primary Structure of Proteins: Refers to the linear sequence of amino acids linked by peptide bonds, determining the protein's unique characteristics.
Secondary Structure of Proteins: Involves local folded structures such as alpha helices and beta sheets, stabilized by hydrogen bonds between the backbone atoms.
Tertiary Structure of Proteins: The overall three-dimensional shape formed by the folding of the secondary structures, influenced by side-chain interactions, including hydrophobic, ionic, and hydrogen bonding forces.
