Application

Carboxylate-modified polystyrene latex beads have been used to collect morphofunctional data about the immune systems of Carabus lefebvrei, a helicophagous Italian endemic ground beetle often used as an indicator of the habitat quality of the Apennines mountain forests. Carboxylate-modified polystyrene latex beads have also been used to inform comparative studies on immunity defense mechanisms of adults and larvae of the coleopteran Cetonischema aeruginosa and to investigate the phagocytic activity of cultured rat thyroid cells.

BACKGROUNDThe role of humoral immunity in COVID-19 is not fully understood, owing, in large part, to the complexity of antibodies produced in response to the SARS-CoV-2 infection. There is a pressing need for serology tests to assess patient-specific antibody response

We investigated the phagocytic activity of cultured rat thyroid cells (FRTL) by using latex beads. FRTL cells ingested many carboxylate-modified polystyrene latex beads (c-latex beads), which had carboxyl residues on the surface, whereas they ingested few polystyrene latex beads (p-latex
