  • Detection And Quality Control Of Host Proteins

    Host proteins (HCP) form a major part of the process-related impurities in the production of biologics. The amount of residual HCP in a pharmaceutical product is often considered a critical quality attribute (CQA) because of its potential to affect product safety and efficacy.

  • Definition And Structure Of Antibodies

    Antibodies are shaped like the letter 'Y' and their main job is to bind to an invading antigen, but not to kill the antigen - they do not have this function; the binding is to give the antigen a marker to be destroyed. When phagocytes find the marker to destroy, they come forward and swallow the antibody-bound antigen and digest it.

  • Selfish Bacterial Plasmids

    Plasmids are a segment of circular DNA within a bacterium that is not part of the bacterial nuclear genome; they replicate within the cell and enter a daughter cell at random when it divides.

Cell Signal Transduction

Signal ligand molecules activate the receptor domain in the cell by binding to the specific domain outside the receptor protein membrane on the cell membrane, so as to transfer the signal from outside the membrane to inside the membrane. This process is called cell signal transduction.

Cell information transmission methods: (1) through direct contact between adjacent cells; (2) through the secretion of various chemical substances by cells to regulate the metabolism and functions of other cells; the chemical substances that regulate the life activities of cells are called information substances. Intercellular information substances are the collective name of chemical substances secreted by cells that regulate the life activities of target cells, also known as first messengers. Mainly include proteins and peptides (such as growth factors, cytokines, insulin, etc.), amino acids and their derivatives (such as glycine, thyroxine, epinephrine, etc.), steroid hormones (such as glucocorticoids, sex hormones, etc.), fatty acids Derivatives (eg prostaglandins), gases (eg nitric oxide, carbon monoxide, etc.).
