A composition comprising an isotonic, buffered aqueous medium containing an optimized concentration of human serum albumin has been found to stabilize irradiated, haptenized tumor cells stored for some period of time after haptenization. In specific embodiments, the viability of the haptenized tumor cells stored in a composition of the invention ranged from about 60% to about 100% greater than the cell viability of cells stored in a prior art solution. In a specific embodiment, 1% human serum albumin in Hank's Buffered Salt Solution was found to stabilize haptenized melanoma cells. Methods of storing haptenized tumor cells and vaccine preparations are also provided.

Compositions, kits and methods are provided for Interferon analogs in order to promote general health or for therapeutic treatment of diseases. Human interferon analogs are made by fusion of interferon with human serum albumin. The bio-assay shows that the interferon analogs with the same cell protection against viral attack have 3-10 times longer acting function than interferon in vivo. These novel long acting interferon analogs can be used in treatment of patients with viral infection, such as SARS virus, HIV, HCV, HBV, or HAV, and the cancer diseases, such as leukemia and malignant melanoma. They also have a 3-5 times longer shelf-life compared with interferon.

A therapeutic preparation, and a process of using the preparation, for the control of tumor growth and immune diseases. The preparation is an immobilized cytotoxic enzyme system which is carried by an insoluble substrate that is administered into the mammalian subject by injection or implantation. The preferred embodiment of the preparation uses a polymerized albumin carrier containing immobilized glucose oxidase and peroxidase. The immobilized enzyme system is prepared in the form of small particles that can be administered either by implantation or by injection into tumor-bearing mammals. To date, antibacterial activity has been demonstrated only in vitro. Intraperitoneal injection into rats bearing Novikoff hepatomas or into mice bearing B16-F1 melanomas or L1210 (Lymphoid) tumors has resulted in the selected killing of tumor tissues. Several daily administrations are required to achieve complete destruction of the tumor. Additionally, the preparation is also active as a stimulant of the specific immune response to neoplasia. Its effect on the immune system could be useful in the stimulation of the immune system in diseases where the action of the endogenous immune system is insufficient.
