摘要：

Using an oligonucleotide d(pT10-C-A) as primer, cDNA has been transcribed from the 3' non-coding region of mouse immunoglobulin light chain mRNA and sequenced by a modification1 of the 'plus-minus' gel method2. The sequence obtained has partially corrected and extended a previously obtained sequence3. The new data contains an unusual sequence in which a trinucleotide is repeated seven times.
