    • The invention provides a method to determine the amount of a target nucleic acid in a sample which comprises (i) mixing the sample with a predetermined amount of a control nucleic acid, the control nucleic acid having a control region which includes at least one primer binding region homologous to a primer binding region in a selected region of the target nucleic acid; (ii) bringing the mixture formed in (i) into contact with at least one nucleic acid primer capable of binding to the primer binding region of the target and control nucleic acids; (iii) performing a nucleic acid amplification reaction, said reaction requiring the presence of the primer to amplify the selected region of the target nucleic acid and the control region of the control nucleic acid; (iv) determining the relative quantities of the amplified control region and selected region nucleic acids; and (v) calculating from the determination of (iv) the amount of target nucleic acid in the sample. The method can be used for the quantitation of a PCR, e.g. using a control nucleic acid which has a centrally located unique restriction site not present in the target nucleic acid. Target nucleic acids may include viral genomes of e.g. CMV.

    • A process for producing adducts of a polymer and a target material which process comprises the steps of (a) reacting either (i) an activating compound of formula (I) X-AM with a polymer of formula (II) (C)c POL - Gg so as to form (ii) a sulphonate ester-activated polymer of formula (III) (C)c POL - (AM)g; (b) reacting the sulphonate ester-activated polymer of formula (III) or (III') with the target material and (c) recovering the adduct of the polymer and the target material, in which process: (i) the polymer of formula (II) is dry as determined by benzene distillation, (ii) the reaction of the compound of formula (I) or (I') with the polymer of formula (II) is conducted in an organic solvent which is inert to the reagents and to the product of formula (III) or (III') and is anhydrous as obtainable using molecular sieves of 0.3nm; (iii) the reaction of the compound of formula (I) or (I') with the polymer of formula (II) is conducted in a reaction vessel from which water is excluded; (iv) the sulphonate ester-activated polymer of formula (III) or (III') so produced is recovered and either used directly in step (b) or stored, prior to use in step (b), in the presence of a desiccating agent more hygroscopic than the product of formula (III) or (III'); and (v) the reaction of the sulphonate ester-activated polymer with the target material is conducted in a non-denaturing medium and non-denaturing temperature with respect to the target material.
