In the present work we compare the results obtained by two approaches to detect receptor expression on cells surface: (i) the confocal laser scanning microscopy, which is an established methodology to study cell biology ...

Physical, chemical and biological agents can act in the DNA, resulting in mutation involved in cancer. Thus, genotoxic tests are required by regulatory agencies in order to evaluate potential risk of cancer. Among these ...

The lethality neutralization assay performed in mice is the standard recommended by the World Health Organization to estimate antivenom potency. The interpretation of its results without considering its analytical capacity ...

This work presents a pipette tip gap closure migration assay prototype tool (semi-adherent relative upsurge—s-ARU—method) to study cell migration or wound healing in semi-adherent cell lines, such as lymph node carcinoma ...

In vitro conservation of chayote (Sechium edule). The in vitro medium-term conservation technique was assayed on chayote. Survival was assayed after the addition of high concentration of sucrose (0, 30, 50, 60, 70 y 80 ...

The biological potential of Vip and Cry proteins from Bacillus is well known and widely established. Thus, it is important to look for new genes showing different modes of action, selecting those with differentiated ...

Transcriptional feedback loops are at the core of the molecular clockworks. As single clock genes were cloned it was compelling to develop an assay that allowed simple and direct functional testing of putative activators ...
