Curdlan is an insoluble natural polymer with linear structure mainly produced by Alcaligenes faecalis. It is a dietary fiber with gelatin properties.
Application
Curdlan from Alcaligenes faecalis has been used:
- for the stimulation of carp macrophages for regulation of differentially expressed genes
- to stimulate human intestinal epithelial cells for cytokine secretion
- to study its effect on transcriptional responses of inflammation/respiratory burst-associated genes in mouse alveolar macrophages by customized reverse transcription (RT)-PCR based arrays
- as a substrate in β-1,3–1,4-Glucanase activity assay
Biochem/physiol Actions
Curdlan is a (1,3)-β-glucan. It is a pathogen-associated molecular-pattern (PAMP) recognized by the receptor dectin-1. Activation of dectin-1, together with TLR2/TLR6, promotes signaling resulting in the production of pro-inflammatory cytokines, thus inducing inflammation.
Curdlan is used as a food additive in the food industry. It improves the elasticity and reduces the embrittling tendency of hydroxyapatite/chitosan scaffold, which aids in bone regeneration.
Preparation Note
For gelation at 70 °C, the concentration of the sodium hydroxide should be 0.01 M.
This product is tested for solubility in 0.1N sodium hydroxide at a concentration of 9.8 - 10.2 mg/mL. Heating and/or sonication are typically required for solubilization. This product is not sterile. For use in cell culture, stock solutions should be filter sterilized prior to use.

Do you test to confirm that product C7821, Curdlan, has (1,3)-β-glucan linkages?
1 answer-
We do not test to confirm that C7821, Curdlan, has (1,3)-β-glucan linkages on a lot to lot basis. However, we have verified product authenticity in the past. Our manufacturing procedure is reported in literature as yielding Curdlan. In addition, C13-NMR, chromatography, and IR analyses results compared to literature and commercial control product proved that product is a (1,3)-β glucan polymer.
