Application

Esterases are ubiquitous in nature and encompass a series of different enzymes acting upon select substrates. With the 90C2 kit, Naphthol AS-D Chloroacetate is enzymatically hydrolyzed by "specific esterase, " liberating a free naphthol compound. This then couples with a diazonium salt, forming highly colored deposits at sites of enzyme activity. This enzyme is usually considered specific for cells of granulocytic lineage. May be used to detect neutrophils in peripheral blood, bone marrow or tissue sections which have been paraffin embedded.

Development of colon cancer is a multistep process that is regulated by intrinsic and extrinsic cellular signals. Extrinsic factors include molecular patterns that are derived from either pathogens (PAMPs) or cellular damage (DAMPs). These molecules can promote tumourigenesis by activation

Right ventricular (RV) dysfunction is a strong risk factor for poor clinical outcome following pulmonary embolism (PE), the third most prevalent cardiovascular disease. Previous studies in our laboratory demonstrated that RV failure during PE is mediated, in part, by neutrophil-dependant

Inactivation of the Hippo pathway protects the myocardium from cardiac ischemic injury. MicroRNAs (miRs) have been reported to play pivotal roles in the progression of myocardial infarction (MI). The present study examined whether miR‑93 could promote angiogenesis and attenuate remodeling
