Abstract
A method for producing a human epidermal growth factor in high yield and high purity by adding particles of an aluminum or magnesium silicate of the formula z.2 (or 6) SiO.sub.2.xH.sub.2 O where Z is Al.sub.2 O.sub.3 or 2MgO and x is the number of water molecules in each molecule of the compound, to human urine under neutral to acid conditions to adsorb the factor on the particles and then eluting the factor with an alkaline solution.
