This discovery resulted when a .lambda. gtll cDNA library of normal human melanocytes were screened with antibodies directed against purified hamster tyrosinase. Sixteen independent clones which gave a positive signal were isolated from 5 x 105 independent plaques. cDNA inserts of 13 clones among the 16 candidates cross-hybridized with each other indicating that they were from related mRNA species. mRNA homologous to a representative cDNA .lambda. mel 34 was expressed specifically in melanocytes, detecting an approximately 2.4 kb mRNA species of human melanocytes. The nucleotide sequence of the three overlapping cDNA inserts spanning 1.88 kb was determined and an amino acid sequence was …

Why it's free to use
- Granted January 7, 1992. A Canadian patent filed before October 1, 1989 lasted 17 years from grant, so its term ended January 7, 2009.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
