GA can promote plant cell elongation, stem elongation, leaf expansion, accelerated growth and development, early crop maturation, and increase yield or improve quality; it can break dormancy and promote germination; reduce organ abscission, improve fruit set or form seedless fruits, etc. Metware Biotechnology has established a method for the analysis of gibberellins based on LC-MS/MS platform with the isotopic internal standard for absolute quantification of 16 GAs for basic life science research.
11 types of internal standards are used to monitor the whole extraction and detection process.
The RSD of 80% of substances less than 20% in three technical replicates, and 100% of them RSD are less than 30%.
The derivatization process improves the separation and sensitivity of different kinds of erythromycin detection.
The gibberellin detection line reaches 1.05pg/mL and the lower limit of quantification reaches 3.50pg/mL.
18 kinds of erythromycin assays, covering the main substances on the pathway.
The method has been published by customers in more than 100 articles in Nat Commun, Plant Cell, PNAs, Plant Journal, Plant Physiology, Molecular Plant, Scientific Reports, Nature plant, and other journals.
