2.2 EXEMPTIONS<br />

2.2.1 The following classes of experiments ((i) - (vii)) are exempt from the guidelines<br />

unless they fall within Categories A or B in Section 4. Such experiments exempt<br />

from the guidelines are classified as Category C (refer also to 4.3).<br />

(i)<br />

(ii)<br />

(iii)<br />

(iv)<br />

(v)<br />

(vi)<br />

(vii)<br />

Experiments involving the fusion of mammalian cells which generate a<br />

non-viable organism, for example, the construction of hybridomas to<br />

make monoclonal antibodies.<br />

Fusion of protoplasts between non-pathogenic micro-organisms.<br />

Protoplast fusion, embryo-rescue, in vitro fertilisation or zygote<br />

implantation in plant cells.<br />

Experiments involving the breeding or use of gene ‘knockout’ mice (i.e.<br />

mice in which the genetic modification involves deletion or inactivation of<br />

a specific gene), independent of whether the mice carry a selectable<br />

marker gene, provided that the marker gene does not confer an<br />

advantage on the animal. If further genetic manipulations are performed<br />

on these ‘knockout’ mice, these are not exempt from the guidelines and<br />

falls within Category B(i) (Risk Group 2).<br />

<strong>Research</strong> involving the introduction of naked nucleic acids into plants or<br />

animals (other than humans), unless the nucleic acid is both<br />

recombinant and able to give rise to infectious agents.<br />

Work involving the introduction of genetically manipulated somatic cells<br />

into animals, unless they are able to give rise to infectious agents.<br />

Experiments involving approved host/vector systems (refer to Appendix<br />

2) provided that the donor DNA:<br />

• is not derived from plant or animal pathogens and that the DNA to be<br />

introduced is characterised fully and will not increase host or vector<br />

virulence;<br />

• is derived from mammalian sources and is used to construct shot-gun<br />

libraries in an approved host/vector system mentioned in Appendix 2;<br />

• does not code for a vertebrate toxin having a LD50 of less than 100<br />

µg/kg;<br />

• does not represent or comprise more than two-thirds of a viral<br />

genome, and is not being used in any experiment in which missing<br />

segments of the viral genome that are essential for infection are<br />

available in the host cell or will become available by further breeding<br />

processes.<br />
