摘要:
The present invention is directed to an isolated and purified, recombinant, unglycosylated and dimeric CSF-1, the dimeric CSF-1 being biologically active and essentially endotoxin and pyrogen-free, the dimeric CSF-1 consisting essentially of two monomeric human CSF-1 subunits. The present invention is further directed to pharmaceutical compositions comprising the same.

Native Type II GAP (GTPase activating protein), its uses in cancer diagnosis, and methods for obtaining and purifying native and recombinant Types I and II GAPs are described.
摘要:
The present invention is directed to a biologically active CSF-1 dimer comprising a first CSF-1 monomer and a second CSF-1 monomer, wherein at least one of the monomers is truncated at the C-terminus after residue position 223. The dimers also include point mutations in one or both of the CSF-1 monomer. The invention also includes pharmaceutical compositions that comprise the CSF-1 dimer in a pharmaceutical excipient.
摘要:
The present invention relates to the production of CSF-1 heterodimers and pharmaceutical formulations of the heterodimers. The heterodimers can be formed using CSF-1 monomers that have variations in sequence, N or C-terminal processing. For example, CSF/C.gradient.150 can be dimerized with LCSF/C.gradient. 190 to form a heterodimer. Dimerization may occur by separately preparing homodimers and mixing them together under the appropriate conditions. Thereafter, homodimers may be separated from the heterodimers by various chromatographic techniques. Once the heterodimers are isolated, pharmaceutical preparations can be prepared.

摘要:
A process for recovering microbially produced IL-2 in a highly pure form from the cellular material of the microorganisms that produced it comprising: disrupting the cell membranes of the microorganisms; extracting the disruptate with a chaotropic agent, such as urea, that selectively extracts microbial proteins from the cellular material; solubilizing the IL-2 in the solid phase of the extraction, mixture with an aqueous solution of a solubilizing agent, such as SDS, containing a reducing agent; and separating the IL-2 from the resulting solution by an optional extraction with 2-butanol or 2-methyl-2-butanol followed by gel filtration chromatography, oxidizing the IL-2 and purifying the oxidized IL-2 by RP-HPLC.
