NATIONAL FOREWORD

This Indian Standard (Part 4) which is identical with ISO/TS 21569-4 : 2016 ‘Horizontal methods for molecular biomarker analysis — Methods of analysis for the detection of genetically modified organisms and derived products — Part 4: Real-time PCR based screening methods for the detection of the P-nos and P-nos-nptII DNA sequences’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Biotechnology for Food and Agriculture Sectional Committee and approval of Food and Agriculture Division Council.

This Indian Standard is published in several parts. The other parts in this series are:

Part 2 Construct-specific real-time PCR method for detection of event FP967 in linseed and linseed products

Part 3 Construct-specific real-time PCR method for the detection of the P35S-pat–sequence for screening for compounds of genetically modified organisms

Part 5 Real-time PCR based screening method for the detection of the FMV promoter (P-FMV) DNA sequence

Part 6 Real-time PCR based screening methods for the detection of cry1Ab/Ac and Pubi-cry DNA sequences

ISO 21569 : 2005 is to be revised by ISO to become the future Part 1.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker
