Zed SRBCs, only rare unopsonized SRBCs appeared bound to ZK1 cells; most cells did not have any unopsonized SRBCs attached. After binding, these unopsonized SRBCs were easily lysed away (Fig. 5A). Approximately 80 of ZK1 cells were positive for FcR-mediated phagocytosis of opsonized SRBCs (Fig. 5B). Similar results were seen in ZK2 and ZK6 clones (data not shown). Decreased binding and phagocytos

Lightly the uptake of fluorescent latex beads by ZK1 cells (Fig. 6B). Furthermore, to determine whether the size of dextran sulfate molecules alters the effect on ZK1 cells' uptake of latex beads, we tested different sizes of DS in the binding/phagocytosis assay. The results indicated thatonly dextran sulfate with smaller molecular weight (5-8kDa) inhibited binding, whereas larger 100-500-kDa dext

Bited a 325-bp PCR product, whereas SR-AI/II-/- mutant allele showed a 434-bp PCR product. MARCO wild type allele exhibited ca. 500-bp PCR product, and MARCO-/- mutant exhibited ca. 850-bp PCR product. All of the three cell lines are stable and Mycoplasma-free by Mycoplasma PCR ELISA test (Roche, Indianapolis, IN) during culture in the past 24 months.SR-AI/IIM WT ZK1 ZK2 ZK6 MMARCOWT ZK1 ZK2 ZKMAR

Tential impact of HIV-1 diversity on both vaccine development and the sustainability of antiretroviral therapies, it is particularly important that molecular epidemiological surveillance is continued in HIV diversity hotspots such as Cameroon. In this study we have focused on characterizing the diversity of gag and nef genes of Cameroonian HIV-1 isolates. These genes are?2013 Tongo et al.; license

Allele primers, amplifies a 434 bp DNA fragment from SRA-deficient ZK1, ZK2 and ZK6 cells. With primers for MARCO wild-type allele, amplifies a 500 bp DNA fragment from WT mice; with primers for MARCO mutant allele, amplifies a 850 bp DNA fragment from ZK cells. ZK1, ZK2 and ZK6 clones exhibited both MARCO and SRA-I/II-deficient. PCR products, ca.10 l/each was resolved on a 1.5 agarose gel by gel

Ovided a very important tool to facilitate biological study of macrophages [20-23]. Several murine macrophage cell lines from bone marrow [24,25], spleen [26,27], fetal liver [28,29], and lung [30] have been successfully obtained by in vitro infection of primary cell cultures with a recombinant J2 retrovirus carrying the v-raf and v-myc oncogenes. In addition, investigation of the function of both

Ing time (mean generation time = mgt) was calculated according the formula: N = N02T/mgt. On the average, doubling time of ZK cell lines is between 12 h to 16 h in RPMI complete medium (Fig. 2). Like their parental primary AMs isolated from the MS-/- mice, all of the cell lines are adherent but trypsin-sensitive for passage.
