| lambda bacteriophage | <virology> Bacterial DNA virus, first isolated from E. Coli. Its structure is similar to that of the T even phages. Lambda genetic material consists of a double-stranded DNA molecule with 5' twelve-base-pair sticky ends, known as cos sites, which permit circularisation of the DNA molecule. It shows a lytic cycle and a lysogenic cycle and studies on the control of these alternative cycles have been very important for our understanding of the regulation of gene transcription. It is used as a cloning vector, accommodating fragments of DNA up to 15 kilobase pairs long. For larger pieces, the cosmid vector was constructed from its ends. (14 Mar 2000) |
| lambda chain | <immunology> Although light chains are found in many multimeric proteins, L chain usually refers to the light chains of immunoglobulins. These are of 22 kD and of one of two types, kappa or lambda. A single immunoglobulin has identical light chains (2 kappa or 2 lamda). Light chains have one variable and one constant region. There are isotype variants of both kappa and lamda. (25 Jun 1999) |
