Compound Description

IsoSep AB isolates the oligosaccharides, glycolipids and gangliosides from mammalian and natural sources. Some oligosaccharides are of synthetic origin. The origin of our compounds is stated in the CoA that accompanies each product upon delivery. For details please inquire to

Synthetically prepared glycoconjugates (neoglycoproteins) are prepared by covalent attachment of the oligosaccharide to the proteins HSA, BSA or KLH. The degree of incorporation of oligosaccharide in the protein is specified in the CoA.

Our compounds have not been subjected to endotoxin screening.

Albumin Conjugates

It should be noted that the linkers APE and PAP are attached to the carbohydrate glycosidically, with the anomeric configuration intact, as shown in the respective substances. The APD linker, on the other hand, is attached to the carbohydrate via reductive amination of the reducing sugar unit, rendering the reducing sugar to be present in the form of an open chain unit, instead of in its original ring configuration.

The conjugates are supplied as freeze dried powders. Storage temperature -20°C.

Synthetic Glycolipids (PA8)

Attachment of the hydrophobic residue phenyl alkyl (C8 or C14) (PA8, PA14) to the oligosaccharide is performed via reductive amination. With this procedure the terminal reducing sugar (glucose) is modified to an open chain unit and is no longer present in its original ring configuration.

One possible application for these substances is as acceptors in glycosyl transferase assays since they are water soluble but have good affinity to C18-silica material.
