Phosphatidylinositol Mannosides 1 & 2

Reagent:
Phosphatidylinositol mannoside, PIM1,2

Default Quantity:
0.5 mg

Production system:
Cells are extracted with either chloroform/methanol/water (10:10:3). The organic soluble fraction is dried and titrated with cold acetone. The acetone insoluble fraction is applied to preparative thin-layer chromatography plates (20cm, Silica gel 60 F254, 1mm) in a solvent system of chloroform/methanol/water (60:30:6). PIMs are extracted from the silica plates and released from the dried matrix using 40% methanol in chloroform.

Notes:
No structural differences between the PIMs of M. tuberculosis and M. bovis are known.
