| Summary, etc | Fresh NR latex contained two major proteins, 14 kD and 24 kD, associated with rubber particles, and a variety of acidic and basic proteins of molecular weights less than 14 kD to greater than 100 kD in the B- and C- serum fractions. Processing the latex to its products changed the composition of these proteins, more so with serum proteins than with rubber particle proteins. Serum proteins most affected were the very acidic and basic proteins of molecular weight greater than 14 kD and isoelectric point (pI) in the pH range of 3.5 to 4.6 and 7.0 to 9.5, respectively. The composition of these proteins was greatly influenced by the storage periods of high ammoniated (HA) latex concentrate, latex compounding ingredients and heating of the latex compound. Thus HA latex concentrate of more than 3-months-old, HA latex concentrate compounded with ZnO and prevulcanised latex contained mainly acidic proteins of pI in pH range of 4.6 to 6.0 and molecular weights less than 14 kD. A similar pattern was found in extractable proteins of NR examination gloves. |
