Abstract: The present invention relates to lyophilized formulations of Stem Cell Factor (SCF) with increased stability. The formulations of lyophilized SCF include amino acid buffers and sucrose. Methods of producing said formulations are also disclosed in the specification.
Abstract: The present invention relates to granulocyte colony-stimulating factor (“G-CSF”) analogs and compositions containing such analogs which retain the three-dimensional structure of the internal core of the four alpha helical bundle of G-CSF. In another aspect, such G-CSF analogs can also be attached with biologically active proteins to form hybrid molecules and still retain G-CSF structural integrity. Also provided are methods for determining and preparing analog or hybrid molecules and modifications.
Abstract: Disclosed is a method of preparing a lyophilized stem cell factor (SCF). The method comprises mixing the SCF with histidine and/or glutamic acid and lyophilizing the formulation. Optionally, a bulking agent or an osmolarity regulating agent is included in the formulation prior to lyophilization.
Abstract: The invention relates to a novel formulation of stem cell factor. The formulation contains histidine, glutamic acid, sucrose and mannitol. The formulation has a pH between 5.0 and 6.0 and has been lyophilized.
Abstract: The present invention relates to stem cell factor analog polypeptide compositions, and vectors, host cells, and processes for recombinant DNA production of the present stem cell factor analogs. Pharmaceutical compositions and methods of use are also disclosed.
