1.1本指南涵盖了识别生物技术中使用的噬菌体λ的程序。 1.2有数百种lambda变体可用于生物技术。这些lambda变体来自野生型lambda，在基因组大小和基因型上有所不同。 1.3如果噬菌体lambda用于构建重组分子，则应使用第5节中规定的相同标准来表征新制备的DNA。

1.1 This guide covers the procedures for identifying bacteriophage lambda used in biotechnology. 1.2 There are hundreds of lambda variants that can be used for biotechnology. These lambda variants are derived from wild type lambda and differ in genome size and genotype. 1.3 If the bacteriophage lambda is to be used to construct a recombinant molecule, then the same criteria as prescribed in Section 5 should be used to characterize the newly made DNA.
