HBD3 regulates matrix metalloproteinase production in human myeloid dendritic cells exposed to Porphyromonas gingivalis hemagglutinin B

Matrix metalloproteinases (MMP) are zinc- or calcium-dependent proteinases involved in the normal maintenance of the extracellular matrix. When elevated, MMPs degrade matrix components contributing to tissue destruction in infected periodontal sites....

Defensin DEFB103 bidirectionally regulates chemokine and cytokine responses to a pro-inflammatory stimulus.

Human ß defensin DEFB103 acts as both a stimulant and an attenuator of chemokine and cytokine responses: a dichotomy that is not entirely understood. Our predicted results using an in silico simulation model of dendritic cells and our observed...

Analysis of wear, wear particles, and reduced inflammatory potential of vitamin E ultrahigh-molecular-weight polyethylene for use in total joint replacement.

Vitamin E (VE) has been added to ultrahigh-molecular-weight polyethylene (UHMWPE) acetabular cups and tibial trays primarily to reduce oxidative damage to the polymer. The aim of this study was to investigate the relative wear rates of...

Which Lonza Bacterial Endotoxin Test (BET), LAL or PyroGene™ Recombinant Factor C (rFC), endotoxin detection kit should I use?

There are a few different things you should consider before deciding which endotoxin detection kit to order. First of all, how many samples will you be testing, and how frequently? If you are going to be testing one or two samples, one time only,...

What equipment do I need to run my Lonza Bacterial Endotoxin Test (BET), LAL or PyroGene™ Recombinant Factor C (rFC), endotoxin detection assay?

Each endotoxin detection assay requires the use of different equipment. If running one of our PYROGENT™ Gel-Clot assays, a non-circulating waterbath or a dry heat block able to heat at 37°C is required. If running one of our kinetic assays,...

Can I get a Material Data Safety Sheet (MSDS) for my Lonza endotoxin detection Bacterial Endotoxin Testing (BET) kit, LAL or PyroGene™ Recombinant Factor C (rFC), and/or my accessory products?

All of our endotoxin detection products have been evaluated and deemed non-hazardous in accordance with 29 CFR 1910.1200, the Hazard Communication Standard, based on the percentage quantities of its constituents. Therefore, none of our endotoxin...

When running a Lonza Bacterial Endotoxin Test (BET), LAL or PyroGene™ Recombinant Factor C (rFC), endotoxin detection assay why should I use glass accesory products instead of plastic?

Endotoxin adheres to plastic surfaces more strongly than to glass surfaces. Therefore, we recommend that you use only borosilicate glass dilution tubes when preparing your Control Standard Endotoxin (CSE) dilutions. In some cases, certain plastics...

When running a Lonza Bacterial Endotoxin Test (BET), LAL or PyroGene™ Recombinant Factor C (rFC), endotoxin detection kit why is it important to vortex my control standard endotoxin (CSE) dilutions?

Endotoxin will adhere to glass surfaces, but this can be counteracted with proper vortexing to ensure that the solution you aliquot into your reaction tubes or microplate has the proper EU/ml concentration. As our package inserts state, the CSE vial...

When performing a Lonza Bacterial Endotoxin Test (BET), LAL or PyroGene™ Recombinant Factor C (rFC), endotoxin detection assay how do I convert from EU/ml (Endotoxin Unit) to ng/ml?

Depending on the source of the endotoxin, the conversion from endotoxin units to nanograms will vary. The FDA initially defined the Endotoxin Unit (EU) as the endotoxin activity of 0.2 ng of Reference Endotoxin Standard, EC-2 or 5 EU/ng. To convert...

When performing a Lonza Bacterial Endotoxin Test (BET), LAL or PyroGene™ Recombinant Factor C (rFC), endotoxin detection assay should I use matched reagents, lysate/CSE?

You need to use matched reagents in order to comply with FDA requirements for endotoxin testing. Each Lonza LAL lot is tested for functionality using United States Reference Standard EC-7. We then match this LAL lot to a lot of our Control...
