Endothelin and Big Endothelin ELISA Assays: Product Highlights



Eagle Biosciences’ Cardiovascular line is a full list of unique assays for the comprehensive determination of important and emerging biomarkers of cardiovascular disease.  Our Endothelin (1-21) ELISA and Big Endothelin-1 ELISA are robust and not only offer direct measurement of these analytes but also provide flexibility to run manually or in an automated system. Collectively, these assays provide a comprehensive means to accurately and easily measure the endothelin system and circulating concentrations of endothelin

EagleBio’s Endothelin Assays offer several key attributes  such as excellent sensitivity, use with multiple sample types, and small sample volume requirements which make these assay kits excellent tools for evolving research in cardiovascular and stress-related fields of study.

Why Measure Endothelins?

The principle actions of endothelin surround increasing blood pressure and vascular tone, thus endothelin antagonists may serve to play important roles in offsetting the negative impact endothelin has in invivo. Both Big ET and ET are strong independent predictors of survival in patients
with congestive heart failure, and identify a population with a very high risk of mortality.  

The biological role of ET extends beyond endothelins’ primary vascular and growth regulatory properties. Due to the complex nature of the endothelin system, further research may be necessary to further define these biological intricacies for the development of therapeutic agents. Robust, sensitive, and specific immunoassays could be valuable tools to assist researchers in these investigations. Read more

Study Summary (1 & 2 above):

Scientists tested the theory that English cocker spaniels(ECS)  have lower serum serotonin
than do aggressive dogs of other breeds. Eaglebio’s
Serotonin ELISA Assay Kit was used to measures serotonin levels in the serum of the canines being studied. It was found that ECSs do in fact have lower serum serotonin
than do aggressive dogs of other breeds making ECS a potential good model to study the neurophysiological mechanisms
underlying impulsive aggression.

Study Summary:

Researchers’ objective for this study was (1) to assess the suitability of different types of blood samples for measuring circulating
serotonin in canine clinical studies, and (2) to investigate the relationship between the serotonergic system
and canine aggression. Eaglebio’s Serotonin ELISA Assay Kit was used to measures serotonin levels in serum, plasma, and platelets in the canine cohort.  The results revealed that the mean serotonin concentration in aggressive dogs was significantly lower than in nonaggressive
dogs in all the assayed samples.

Study Summary:

Researchers sought to perform an in-depth investigation of the biological basis of aggression in canine to provide new and improved diagnostic and therapeutic approaches for this frequent problem. Eaglebio’s Serotonin ELISA Assay Kit was used to measure serotonin levels in the serum of the canines being studied.  Aggressive animals showed significantly higher plasma
concentrations of cortisol than non-aggressive dogs suggesting that aggressive dogs might differ
from non-aggressive dogs in the activities of the serotonergic system and the HPA axis.

Study Summary:

The objective of this study was to assess the effect of a 30-day-long fluoxetine treatment on the
peripheral serotonergic system and the HPA axis in canine aggression. EagleBio’s Serotonin ELISA Assay Kit was used to measure concentrations of serum serotonin. Other analytes such as plasma cortisol and
dehydroepiandrosterone (DHEA) were also quantified in a group of aggressive and non-aggressive dogs. The results revealed that treatment of aggressive dogs caused a drop in serum 5-HT concentrations in both
groups, supporting the hypothesis that the peripheral serotonergic
system in canine species is sensitive to drugs that work
upon the central serotonergic system.

A recent video titled, Immune System- Natural Killer Cells shared on Labroots demonstrates the unique and vital biological role that the natural killer cells (NK cells) have on overall health and its intricacies with the human body.  The complexity of these cells and their powerful impact on the innate immune system are what make these cells so interesting.  

NK cells are a type of cytotoxic lymphocyte its role in immunity is similar to that of cytotoxic T cells in the adaptive immune response. NK cells provide rapid responses to viral-infected cells and respond to tumor formation by releasing their toxins without having to recognize specific antigen before destroying the infected cell.  Hence, these cells are called natural killers. Typically,immune cells detect major histocompatibility complex (MHC) on infected cell surfaces, thus triggering cytokine release, causing cell lysis or cell death (apoptosis).  NK cells are unique because they can recognize stressed cells in the absence of antibodies or MHC which creates a quicker immune response.  Learn more

MDA Oxidized LDL ELISA Assay Published in Obesity Research and Clinical Practice Journal

A recent study was conducted at Medical Sciences Research Centre, Autonomous University of the State of Mexico citing EagleBio’s MDA Oxidized LDL ELISA Assay Kit, a kit designed for the quantitative determination of human MDA Oxidized LDL in serum or plasma. This assay is part of our Oxidative Stress Assay Kit Line which is a comprehensive group consisting of a numerous valuable products for assisting scientists in fields of research such as diabetes, cancer, aging, and other similar areas of study. See the product page below for full details on the kit or view the links below to find a new publication referencing our MDA Oxidized LDL ELISA Assay Kit.  

Publication:

Laguna-Camacho, Antonino. “Direct effects of fatty meals and adiposity on oxidised low-density lipoprotein.” Obesity Research & Clinical Practice 2015: 9(3): 298-300.

Study Summary:

The objective of this study was to track high-fat meals during a four week period to observe and study the effects of sustained frequency change on adipostiy and oxidized LDL. EagleBio’s MDA Oxidized LDL ELISA Assay Kit was utilized to measure Malondialdehyde (MDA)-modified Apo B in human serum.  The findings indicated that changes in frequency of consumption of high-fat eating episodes correlated directly with changes in adiposity and oxidized Low-density lipoprotein (ox-LDL). Hence the number of fatty meals consumed by people with overweight or obesity in few weeks could affect the atherogenic process.

A recent publication in Clinical Cancer Research revealed some
ongoing pancreatic cancer research identifying key cancer biomarkers for developing laboratory tests
for early detection. Researchers have discovered three proteins that people with
pancreatic tumors continuously shed into the urine: LYVE-1, REG1A and
TFF1. The scientists at Bart’s Cancer
Institute in London who have been conducting these studies have sought to purse
these new markers in hopes to discover more reliable, accurate, and noninvasive
means to diagnose pancreatic cancer. Read More
