Check the antibody’s datasheet on the manufacturer’s website for available pictures of Immunofluorescence staining stainings and compare them with your expectations or other published illustrations. Take notice of the antibody’s clonality, asmonoclonal antibodiesspecifically bind to only one epitope, ...
X chromosomes are not inactivated and the dosage of X-linked genes is excessive in KS FGCs. X-linked genes dominate the differentially expressed genes and are enriched in critical biological processes associated with the developmental delay of KS FGCs. Moreover, aberrant interactions between Sertoli ...

Molecular methods of species delineation are rapidly developing and widely considered as fast and efficient means to discover species and face the 'taxonomic impediment’ in times of biodiversity crisis. So far, however, this form of DNA taxonomy frequen
In material chemistry, the coordination number is generally defined as the number of atoms attached to central ion. In a solid-state, it can be defined as the number of atoms attached to another atom. For different unit cells, the coordination number is also different...
Baby sea turtles don't have x or y chromosomes that determine their gender. Instead, external conditions such as temperature play a primary factor as to whether they emerge from their egg as a male or female turtle. But it's not easy to tell a baby sea turtle's gender as they aren't...
