Beta-glucan peptide (BGP)

Beta-glucan from Trametes versicolor - β(1➝4,1➝3, 1➝6)-glucan

Beta-glucan peptide (BGP) is a high molecular weight (~100 kDa)  polysaccharide extracted from the fungus Trametes versicolor.

BGP consists of a highly ramified glucan portion, comprising a beta 1-4 main chain and beta 1-3 side chain, with beta 1-6 side chains covalently linked to a polypeptide portion rich in aspartic, glutamic and other amino acids.

BGP activates murine macrophages and HEK-Blue™ Dectin-1 cells. Detection of β-glucans by Dectin-1 receptor leads to the CARD9-dependent activation of NF-κB and MAP kinases.

Details

Responses to β-glucans.
RAW-Blue™ cells and HEK-Blue™ mDectin-1 cells, which express the mouse dectin-1a gene, were stimulated with 100 µg/ml of various β-glucans.
After 24h incubation, NF-κB activation was assessed by measuring the levels of SEAP (secreted embryonic alkaline phosphatase) using the QUANTI-Blue™ assay.

Stimulatory activity of Dectin-1 ligands:
HEK-Blue™ hDectin-1a and HEK-Blue™ hDectin-1b cells were stimulated with 1 µg/ml or 10 µg/ml Dectin-1 ligands, respectively, and 10 µg/ml TDB.
After 24h incubation, Dectin-1-induced NF-κB activation was assessed by measuring the levels of SEAP using the QUANTI-Blue™ assay.
