| Research Abstract |
(1) Cloning of human GMF-gamma cDNA
We isolated a human GMF-gamma cDNA from human fetal brain cDNA library. One of the clones contained a 573 nucleotide long insert and an open reading frame of 426 bp encoding a deduced protein of 142 amino acids.
(2) Expression of human GMF-beta and GMF-gamma
The cDNA of human GMF-beta and GMF-gamma were inserted to pAED4 expression vector and introduced to E. coli BL21(DE3). The expressed proteins were purified and subjected to antibody production.
(3) Production of anti-human GMF-beta and GMF-gamma antibodies
Recombinant human GMF-beta and GMF-gamma were used as immunogens for the production of polyclonal antibodies. The each anti-serum recognized human GMF-beta and GMF-gamma respectively, but either of them did not react to rat GMF-beta or GMF-gamma.
(4) Cloning of rat GMF-gamma cDNA
We isolated a rat GMF-gamma cDNA from rat pulmonary artery cDNA library. One of the clones contained a 553 nucleotide long insert and an open reading frame of 426 bp encoding a deduced protein of 142 amino acids.
(5) Expression of rat GMF-beta and GMF-gamma
The cDNA of rat GMF-beta and GMF-gamma were inserted to pAED4 expression vector and introduced to E. coli BL21(DE3). The expressed proteins were purified and subjected to antibody production.
(6) Production of anti-rat GMF-beta and GMF-gamma antibodies
Anti-rat GMF-beta and GMF-gamma serum were produced by the same way of human GMF-beta and GMF-gamma. The anti-sera recognized rat GMF-beta and GMF-gamma respectively.
