Recombinant anti-erbB2 immunotoxins containing Pseudomonas exotoxin.
Immunotoxins were made using five different murine monoclonal antibodies to the human erbB2 gene product and LysPE40, a 40-kDa recombinant form of Pseudomonas exotoxin (PE) lacking its cell-binding domain. All five conjugates were specifically cytotoxic to cancer cell lines overexpressing erbB2 protein. The most active conjugate was e23-LysPE40, generated by chemical crosslinking of anti-erbB2 ...
متن کاملNovel anti-CD30 recombinant immunotoxins containing disulfide-stabilized Fv fragments.
PURPOSE To develop a novel targeting reagent to CD30 expressed on Hodgkin'sdisease and anaplastic large cell lymphoma, we made a panel of recombinant immunotoxins specific for CD30 using Fvs of newly produced anti-CD30 monoclonal antibodies (MAbs) and a M(r) 38,000 truncated mutant of Pseudomonas exotoxin. EXPERIMENTAL DESIGN A group of MAbs against CD30 was produced and characterized for the...
متن کاملPseudomonas exotoxin: recombinant conjugates as therapeutic agents.
Pseudomonas exotoxin: structure and function Pseudornonas exotoxin (PE) is a bacterial protein produced by €3. aeruginosa that is toxic for most mammalian cells [for reviews see 1, 21. The mature protein is a proenzyme and, after activation, exhibits both NAD hydrolase activity and ADP-ribosyltransferase activity. When added to mammalian cells the toxin binds to the alpha 2-macroglobulin recept...
متن کاملImmunotoxins made with a recombinant form of Pseudomonas exotoxin A that do not require proteolysis for activity.
We used recombinant DNA technology to construct a mutant form of Pseudomonas exotoxin A (PE) called cysPE35 that contains amino acids 280-364 and 381-613 of PE. cysPE35 begins at the native PE proteolytic cleavage site and contains a single cysteine residue at position 287 that can be used to conjugate the toxin to monoclonal antibodies (MAbs). Unlike immunotoxins containing larger mutant forms...
