General description

The Lewis b (Leb) antigens are widely expressed in the proximal colon. During fetal development, Leb antigens are found throughout the colon, but after birth, they gradually diminish in the distal colon.[1]

Application

Lewis-b tetrasaccharide has been used to treat the P protein for complex crystal growth.[2]

Biochem/physiol Actions

The Lewis b (Leb) antigen reappearance is an excellent tumor marker for discriminating between malignant and benign tumors, and it can also be used in many cases of colon cancer.[1]

Other Notes

Lewis-b human blood group determinant.

Review of O-Linked Glycoproteins

O-Linked glycoproteins are usually large proteins with a molecular mass of >200 kDa. Glycosylation generally occurs in high-density clusters and may represent as much as 50-80% of the overall mass.
