The (pro)renin receptor [(P)RR] is implicated in organ pathology. We examined the cellular location of the (P)RR and whether a putative (P)RR antagonist, RILLKKMPSV, corresponding to the handle region of the prorenin prosegment (handle region peptide [HRP]) influences angiogenesis, inflammation, and neuronal and glial function in rat retina. The (P)RR was localized to retinal vessels, endotheli...

The main objective of this study was to determine the pathways by which horseradish peroxidase (HRP) can cross the endothelium of muscle capillaries. Specimens of mouse diaphragm were fixed for cytochemical analysis at various intervals after intervenous injection of 0.5 mg HRP, at 4 min after intervenous injection of varied amounts of HRP, and at 4 min after intervenous injections in various ...

Horseradish peroxidase (HRP), an enzyme internalized by fluid phase pinocytosis, has been used to study the process by which pinosome contents are delivered to lysosomes in Chinese hamster ovary cells. Pinosome contents were labeled by allowing cells to internalize HRP for 3-5 min. Following various chase times, cells were either processed for HRP and acid phosphatase (AcPase) cytochemistry or ...

Horseradish peroxidase (HRP) was injected intracerebrally to immature rats, once a day for 3 days. The animals were killed 24 hr after the last injection and the cellular and intracellular localization of the enzymatic tracer in the cerebral cortex was investigated by ultrastructural cytochemistry at the light and electron microscopic level as well as biochemically. By light microscopy it could...

background: zoonotic cutaneous leishmaniasis (zcl) is an increasing public health problem in some endemic re­gions. horseradish peroxidase (hrp) conjugated rabbit anti- rhombomys opimus ( r. opimus ) ig is needed for im­munoblotting and elisa tests used to explore the immune response of the rodents against the sand fly saliva. in this study, the production of hrp conjugated rabbit anti- r. opim...

BACKGROUND Our aim was to investigate the potential of the DustGun aerosol technology integrated with the isolated, perfused, and ventilated lung of the rat (IPL) to study the pulmonary disposition of an inhaled model biopharmaceutical, the 40-kDa protein horseradish peroxidase (HRP). METHOD The DustGun aerosol technology was used to deliver respirable powder aerosols of HRP (the mass median ...

The distribution of immune complexes has been studied in mouse spleen stimulated to contain many germinal centers (GC's). Horseradish peroxidase (HRP)-anti-HRP complexes were used as an appropriately precise and sensitive model. We were primarily interested in the relative abilities of three cell types to interact with complexes: lymphocytes, macrophages, and follicular dendritic cells (FDC's)....

As a well-known toxic pollutant, sulfide is harmful to human health. In this study, a simple and sensitive amperometric inhibitive biosensor was developed for the determination of sulfide in the environment. By immobilizing nanoporous gold (NPG) on glassy carbon electrode (GCE), and encapsulating horseradish peroxidase (HRP) onto NPG, a HRP/NPG/GCE bioelectrode for sulfide detection was success...

Correspondence to be addressed to: Dr.T.G. Shrivastav, E-mail:[email protected] Summary Preparation of horseradish peroxidase (HRP) carbamide that is HRP linked to urea (HRP-carbamide/HRP-U) is demonstrated and its potential application in the development of enzyme immunoassays (EIAs) for haptens is described. In this new strategy, the lysine residues of HRP were acylated and then acylat...
