Abstract

The qualitative and quantitative changes of two kinds of lectin (WGA, PNA) binding glycoproteins in early pregnant rabbit uterine fluid (D4-D12) were measured by Western blot and Video densitometer scanning methods. During peri-implantation stage (D6, D7 and D9), there are two WGA binding glycoproteins with MW about 42 kd, 28 kd and a PNA binding glycoprotein with MW 75 kd. It is suggested that the three proteins are stage-specific glycoproteins in rabbit uterine fluid in the course of implantation.
