Preliminary Study of Partial cDNA Cloning for Human Clotting Factor Ⅷ / 第三军医大学学报

A cDNA library prepared from human liver was screened for Factor Ⅶ,a clotting factor in the middle phase of blood coagulation,with P114.12 probe.3 recombinant phages were distinguished,and one of the 3recom-binants was further analyzed and extended by 450 bp as compared with the p114.12 probe.The clone 1 (FⅧhc1) was sequenced and homology between 210 bp of FⅧhc1 and 5559-5769 in FⅧ cDNA was found.It was shown that the FⅧhc1 extended forwardly 800~900bp from 17 exon of FⅧ cDNA.
