Abstract
Monoclonal antibodies that recognize a structure common to human interleukin-2 and to the light .lambda. chain of human immunoglobulin and lines of hybridoma cells that produce these monoclonal antibodies can be prepared by immunizing animals, especially mice, with human interleukin-2 (TCGF) and fusing the splenocytes obtained from the animals with animal, expecially mouse, myeloma cells to create a hybridoma. The hybridomas are raised as clones and the antibodies obtained from the individual clones tested for their specificity to human interleukin-2 (TCGF). Clones that produce antibodies with a specificity to human interleukin-2 (TCGF) are selected for further raising to prepare the antibody. The antibody is harvested from the culture medium or from the ascitic fluids of the animal, especially the mouse, with the hybridoma.

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.
