Latest Patents

Darell Sleep's latest patents focus on the process of high-purity albumin production. The first patent describes a method for preparing albumin from a yeast culture medium that is essentially free of colorants, metal ions, human proteins, host proteins, fragments of albumin, polymers or aggregates of albumin, and viruses. This process ensures that the albumin produced is non-glycated, relatively high in free thiol, and maintains an intact C-terminus. The method involves separating the yeast from the culture medium to yield an albumin solution, followed by a series of chromatography techniques to purify the albumin.

The second patent also outlines a process for high-purity albumin production, emphasizing the use of transformed yeast. This method includes passing the albumin through positive mode cation exchange and anion exchange chromatography. Additional steps such as ultrafiltration and gel permeation chromatography may also be employed to enhance the purity of the albumin.
