Latest Patents

Woltmann holds a patent for a process that involves the preparation of a colloidal solution of human serum albumin. This process includes mixing an aqueous solution of human serum albumin with a non-ionic surface-active agent and an acid solution of a tin(II) salt. The pH is adjusted to a range of 3.5 to 8.0, followed by heating at a constant temperature between 45°C and 100°C until complete hydrolysis of the tin(II) salt and denaturation of the albumin occur. The resulting colloidal solution can also be lyophilized. By treating the solution or the lyophilizate with a ^99mTc-pertechnetate solution, a colloidal preparation is obtained for scintigraphy of the reticuloendothelial system or the lymphatic system. This process allows for selective colloid production with varying particle sizes.
