Fig. 6From: Establishment of a sticky, large, oval-shaped thrombocyte cell line from tree frog as an ancestor of mammalian megakaryocytes cd41 expression in FUHEN cells. The partial coding sequence of cd41 (integrin alpha 2b) was cloned (NCBI accession no. LC027926). Degenerate PCR primers amplified a DNA fragment with a predicted size of 312 bp (a). The alignment of corresponding cd41 sequences in Hyla japonica (LC027926), Xenopus laevis (NM_001094754), Xenopus (Silurana) tropicalis (XM_012952892), Danio rerio (BC163305) and Mus musculus (BC137570) is indicated (b). The alignment was carried out using GENETYX-MAC software (Genetyx Co. Ltd., Tokyo, Japan). The cloned DNA fragment (262 bp) had 67 % homology to Xenopus laevis alpha 2b. The underlined amino acids indicate the integrin alpha superfamily domainBack to article page
