15、ld by AFNOR. This European Standard shall be given the status of a national standard, either by publidon of an identical text or by endorsement, at the latest by April 1998, and conflicting national standards shall be withdrawn at the latest by April 1998. This European Standard has been prepared un

16、der a mandate given to CEN by the European Commission and the European nee lirade Association, and supports esential requirements of EU Dre b) design and review of sampling protocol; c) execution of the sampling protocol d) appropriate record keeping. Responsibilities should be assigned for each ste

17、p to a specific person. The sampling strategy should be reviewed reguiarb, in the light of field inspections, to ensure its continuing validity. 6.2 Design criteria The design of the sampling protocol should meet dened objectives as determined by the investigator and/or by statutory requirements. Th

18、e design can vary widelx for example, requirements for triais of introduced traits see 4a), for studies of gene transfer see 4b)l or gene behaviour see 4c)l can differ. The protocol for sampling should be part of the preparation and design of the experiment, keeping the flexibility that could be req

19、uired by unexpected observations, and should therefore be supported by a clear design of the experiment The sampling protocol should be documented. Parameters such as when sampiing will take place, the location(s) andor site size, the number of genotypes, number of plots and means of plot identifica

20、tion and the number of treatment(s) are important in the development of the design There are many different techniques available for the detection and identification of genetically modified plants. The following should be considered in the initial phase of the design - will samples be used for quaii

21、tative or quantitative analysis? - will sampling be for expressed charaderistics andor target nucleic acids? - which identification andor detection methods will be applied to the samples? - is the sampiing destructive? - is the protocol practical and feasible? The expression of characteristics in ge

22、netically modified plants is further dependent on the following factQm: - genetic background; - developmental stage of the plant; - plant part of relevance such as whole plant, root, leaf, flower, stem, pollen, seed; - specific environmental or externai constraints on the behaviour of the traits. O

23、BSI 1998 STD-BSI BS EN 12305-ENGL 1998 1bZqbbS Ob89712 TZV Therefore, the following should be considered in the design of a representative and statistically valid sampling protocol - choice of appropriate statistical method - required level of significance; - timing and frequency of sampling; - part

24、 of the plant to be sampled; - separate or pooled samples; - stability of sample; - number and size of samples; - number of plots; - number of plants; - number of samples per plot; - number of samples per plant; - appropriate negative and/or positive controls. The labelling of the samples and the sa

25、mpling of appropriate controls, if necessary, should also be described in the protocol. It should contain clear information on transport and storage requirements of the samples. The storage should be appropriate for the subsequent analysis. Appropriate data should be kept for a reasonable period to

26、allow future inspection: these should include records relating to responsibilities for steps of the protocol. In some cases it is appropriate to keep samples so that they can be tested at a later time. 6.3 Execution of sampling protocol To ensure valid quality assurance and sample traceability durin

27、g the sampling, the investigator should: - collect samples in accordance with the sampling design; - idenQfy and label the samples in accordance with the sampling design; - use precautions to protect the integrity of each sample; - store the samples so that they are not degraded with respect to thei

28、r content of specific DNA or gene products; - keep records of the relevant information regarding the sampling; - record every deviation from the initiai design. Page 5 EN 12305:1997 6.4 Record keeping A record should be kept of ail aspects of sampling as foreseen by the sampling design, including th

29、e following: - identification of the experiment; - date and duration of the sampling; - part of the plant; - location of sample (as precisely as necessary); - sample number, - treatment of sample after the collection; - identity of the person collecting samples; - deviations from the protocol; - sto

30、rage and transportation; - observed anomalies of plants.
