The coding regions of Ag85B MPT-64, and ESAT-6 secreted proteins were cloned initially into the eu-karyotic expression vector pJW4303, then transformed to E. coli Top 10 strain for plasmid DNA extraction and further a...
The distribution of Ca2+ in the anthers of wheat was observed using cytochemical method of potassium antimonite. At the later tetrad stage, Ubisch bodies carrying Ca2+ were observed on the inner surface of tapetum, in...
In order to understand the role of Le+Y oligosaccharide antigen (Le+Y) during implantation, the relationship of Le+Y on the cell surface with matrix metalloproteinase (MMPs) secreted by blastocysts and monolayer epith...
Articular cartilage is an avascular and non-nervous tissue. The transport of metabolites to and from the chondrocytes has to take place through the matrix and hence depends on its composition and structure. A major pa...
Atrial natriuretic peptide (ANP)is a peptide hormone secreted by atrial cardiocytes of mammals. It has several powerful functions such as natriuresis, diuresis and vasodilatation. It is expected that ANP may be the be...
Bovine growth hormone (bGH), a 22,000 mol wt protein, which is synthesized and secreted by the anterior pituitary lobe, is necessary for normal growth and development. Fresh bovine pituitaries were obtained from a fac...

Insect chorion (eggshell) is formed by condensation and solidification of the chorionins secreted by the follicle cells around an oocyte which is thus completely wrapped. The surface of the chorion is copied by the in...
Ⅰ. INTRODUCTION During the course of ovary development of insect, a layer of vitelline membrane is secreted by follicle cells around an oocyte after the yolk is deposited in the oocyte. Then, the oocyte begins to tak...
