I found this reference but I can not download it.

De Belder, A.N. and Gratath, K.A., Carbohydrate Res., 30, 375 (1973).

If you have access to an older cell biology methods books i'm sure you can find a protocol there. But since dextrans are polysaccharides I think you can label them in the same way as LPS, it's worth a try.
