PolysacDB ID | 2605 |
Carbohydrate Name | Capsular polysaccharide (Drugpedia) |
Carbohydrate Class | Capsular polysaccharide |
Microbe | Cryptococcus neoformans Serotype D (NCBI Taxonomy) (Drugpedia) |
Basic Structure | The capsular polysaccharide has a linear α-(1-->3)-linked mannose backbone that is substituted with nonreducing D-xylosyl and D-glucuronosyl acid groups. The mannose backbone is partially O-acetylated
|
BCSDB Structure | 136943 |
Proposed functions | The capsular polysaccharide is an important virulence factor |
Antigenic Nature used to produce antibodies | Glycoconjugates |
Carrier Name | Keyhole limpet hemocyanin |
Conjugation Method | Forty milligrams of crude polysaccharide was dissolved in 4 ml of physiological saline solution (PSS). One milliliter of 1% cyanuric chloride in dimethylformamide was added to the polysaccharide solution and stirred for 1 h at 48°C. KLH in PSS (100 mg/2ml) was added and stirred for 1 h at 258°C, and the solution was then incubated at 48C for 18 h. The solution was dialyzed against water for 30 h and centrifuged. The protein concentration in the supernatant was adjusted to 2 mg/ml, 1/9 volume of 10% aluminum potassium sulfate solution was added, and the pH was adjusted to 6.5 with 10% sodium carbonate. The precipitated antigen was removed by centrifugation and resuspended in PSS |
