Snellman, Sylven and Jul n have isolated what appears to be the plasma co-factor from tissue, mast-cell cytoplasm. The co-factor was a lipoprotein containing lecithin, cholesterol, and neutral fats, together with a low molecular-weight polypeptide. Only the six amino acids cysteine, threonine, tyrosine, glycine, leucine, and tryptophan were present in the polypeptide.

In addition to rubber, latex contains 0.3-0.7% ash, 1-2% nitrogenous compounds, 2% resins, and 1-2% sugars and related compounds. The proteins represent most of the nitrogenous compounds in the latex and upon hydrolysis yield alanine, aspartic acid, dihydroxyphenylalanine, glutamic acid, histidine, leucine, ornithine, hydroxyproline, tyrosine, and valine. Lecithin, glycerophosphoric acid, fatty acids (palmitic, stearic, arachidic, oleic, and linoleic), sterols, resin acids, wax, and quebrachitol are some of the other nonrubber constituents. The mineral constituents present in the ash consist of potassium, magnesium with traces of copper, iron, and manganese.
