The binding of concanavalin A to the plasmalemma of higher plants has been studied using protoplasts of two species. The lectin aggregates both tobacco (Nicotiana tabacum L.) leaf protoplasts and protoplasts prepared from a suspension cell culture of grapevine (Vitis vinifera L.). Differences in
Organelles isolated from leaves of spinach (Spinacia oleracea L.) were prefixed in glutaraldehyde and then incubated with ferritin conjugates of four lectins - Concanavalin A (Con A), Ricinus communis L. agglutinin, MW 120,000 (RCA), soybean agglutinin (SBA), and wheat germ agglutinin (WGA) - in
cDNA of human fibroblast growth factor 8 isoform b (FGF8b) was cloned for the first time into a plant expression vector with or without endoplasmic reticulum retention signal (KDEL) and was transiently expressed as His tagged fusion protein in Nicotiana tabacum leaves through Agrobacterium mediated
Gaucher disease is caused by a deficiency of the enzyme glucocerebrosidase (GCase). Currently, enzyme-replacement therapy using recombinant GCase produced in mammalian cells is considered the most effective treatment. Plants are an attractive alternative host for recombinant protein production due
When cell-wall invertase (CWI) from Nicotiana tabacum L. cell-suspension cultures, either non-transformed or transformed with Agrobacterium tumefaciens, was salt-eluted from intact cells and purified on Sulfopropyl-Sephadex (SPS) by pH-gradient elution, the enzyme lost about 50% of its activity
Optical microsurgical techniques were employed to investigate the mechanical properties of Hechtian strands in tobacco (Nicotiana tabacum) and Ginkgo biloba callus cells. Using optical tweezers, a 1. 5-microm diameter microsphere coated with concanavalin A was inserted though an ablated hole in the
