Abstract
The invention relates to cDNA genetic sequences, vehicles containing same as well as hosts transformed therewith, for the production of chimeric immunoglobulin molecules, functional fragments thereof and immunoglobulin derivatives exhibiting novel functional properties comprising human constant region modules and non-human variable region modules, or for class switching antibody molecules and/or chains. The invention also relates to DNA coding for pectate lyase signal peptide has been cloned on a plasmid to create a secretion vector which is capable of producing a chosen protein which is transported across the bacterial membrane. The secretion vector has been used to secrete extracellular thaumatin and extracellular chimeric antibody fragments. The proteins produced by this vector have biological activity. The thaumatin is properly folded and the antibody fragments are capable of binding antigens on target cancer cells. The invention also relates to the secretion of chimeric antibodies and fragments thereof from yeast in functional form.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
