Repair of the endothelial cell barrier after inflammatory injury is essential for tissue fluid homeostasis and normalizing leukocyte transmigration. However, the mechanisms of endothelial regeneration remain poorly understood. Here we show that the endothelial and hematopoietic developmental transcription factor Sox17

Interactions between a host and a bacterial pathogen are mediated by cross-talk between molecules present on, or secreted by, pathogens and host binding-molecules. Identifying proteins involved at this interface would provide substantial insights into this interaction. Although numerous studies have

Protocolli

TRI Reagent® Protocol

TRI Reagent enables simultaneous DNA, RNA, and protein isolation with sample prep guidelines and troubleshooting.

Protocollo per l’uso di TRI Reagent®

TRI Reagent è un reagente che permette non solo di isolare l’RNA in un solo passaggio ma anche il DNA, l’RNA e le proteine dallo stesso campione. In questo protocollo si descrivono la preparazione dei campioni, l’estrazione dei diversi precipitati e la risoluzione dei problemi.

Il team dei nostri ricercatori vanta grande esperienza in tutte le aree della ricerca quali Life Science, scienza dei materiali, sintesi chimica, cromatografia, discipline analitiche, ecc..
