Explore how neutrophils shape the immune response in health and disease. This poster highlights neutrophil pathogen defense mechanisms, including phagocytosis, degranulation, and NETosis, as well as neutrophil roles in inflammation and NET-associated pathologies.
DOWNLOAD NOWAcyclovir-d4 is intended for use as an internal standard for the quantification of acyclovir (Item No. 14160) by GC- or LC-MS. Acyclovir is a guanosine analog that has antiviral activity in vitro against the herpes simplex viruses, varicella zoster virus, Epstein-Barr virus, cytomegalovirus, and human herpes virus 6 (ID50s = 0.1-63.1 μM).1 It diffuses freely into cells and is selectively converted into acyclo-guanosine monophosphate by a virus-specific thymidine kinase. During DNA replication, the phosphorylated form of acyclovir is preferentially incorporated into viral DNA, resulting in premature chain termination and inhibition of further DNA polymerase activity.2 Acyclovir (5 mg/kg) reduces viral titers in mice infected with the herpes simplex virus-1 (HSV-1) strain SC16.3
