Technology
Emission of electromagnetic energy with a shorter frequency (longer wavelength) than that of the incident monochromatic light. Arises from the low probability absorption of quanta with a higher energy than that required for a transition: the difference in energy is emitted as a lower frequency (energy) photon. Allows analysis of vibrational and rotational energy levels using visible incident light.
Indicators
A broad-spectrum semi-synthetic aminoglycoside antibiotic, derived from kanamycin with antimicrobial property. Amikacin irreversibly binds to the bacterial 30S ribosomal subunit, specifically locking 16S rRNA and S12 protein within the 30S subunit. This leads to interference with translational initiation complex and misreading of mRNA, thereby hampering protein synthesis and resulting in bactericidal effect. This agent is usually used in short-term treatment of serious infections due to susceptible strains of Gram-negative bacteria.

Indicators
Complement C2 (752 aa, ~83 kDa) is encoded by the human C2 gene. This protein is involved in post-translational protein processing and complement activity.

Indicators
A broad-spectrum aminoglycoside antibiotic produced by fermentation of Micromonospora purpurea or M. echinospora. Gentamicin is an antibiotic complex consisting of four major (C1, C1a, C2, and C2a) and several minor components. This agent irreversibly binds to the bacterial 30S ribosomal subunit. Specifically, this antibiotic is lodged between 16S rRNA and S12 protein within the 30S subunit. This leads to interference with translational initiation complex, misreading of mRNA, thereby hampering protein synthesis and resulting in bactericidal effect. Aminoglycosides are mostly ineffective against anaerobic bacteria, fungi and viruses.
Indicators
A nonessential amino acid derivative formed during post-translational protein modification through hydroxylation of the amino acid proline by the enzyme prolyl hydroxylase which requires vitamin C as a co-factor. Hydroxyproline is a major component of the protein collagen and plays a key role in the stability of the collagen triple helix. It can be used as an indicator to determine the amount of collagen. Increased hydroxyproline levels in the urine and/or serum are normally associated with degradation of connective tissue. Vitamin C deficiency decreases the conversion of proline to hydroxyproline, which leads to reduced collagen stability.
Glossary Term
EU Regulation 2017/746 governing in vitro diagnostics, which replaced the IVDD with stricter evidence, post-market surveillance, and reclassification rules. Products legacy-listed under the IVDD may still carry transitional timelines, so registration status should be verified per product and per market.
