Technical Support

Humic acid is an important component of organic matter in soil and water, and serves as a plant regulator. Humic acid has multiple reactive activities such as surface adsorption, ion exchange, and complexation. Humic acid can enhance pyrene degradation by Mycobacterium NJS-1. Humic acid can inhibit the activity of superoxide dismutase and scavenge hydroxyl radicals. Humic acid is also toxic to CEM cells.

Description

In Vitro

Humic acid (10 mg C/L; 10 days) in unicellular Microcystis aeruginosa cultured under high iron condition can reduce the content of extracellular polysaccharides and the average colony size, inhibiting colony formation^[2].
Humic acid (1-100 nM; 72 h) exhibits cytotoxicity against acute T lymphoblastic leukemia CEM cells^[3].
Humic acid (0-500 mg/kg) increases root dry weight in Calendula officinalis, chili peppers, and strawberries, and significantly enhances the fruit number and weight of strawberries^[4].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
