Know All About Occludin Antibody

Occludin is a 65-kDa protein that is found in various forms that are phosphorylated. They range from to around 82 KDa. Occludin may play a role in controlling both the location and function of the occludin. Polyunsaturated fat acids are believed to increase the expression of occludin by increasing the resistance of the transendothelial cell as well as reducing the cell’s resistance to larger molecules.

The amount of occludin is different significantly depending on the tissue. In the brain occludin is large and constantly expressed at contact points, while non-neural tissues exhibit lower levels of expression and a discontinuous distribution. You can visit to know about Occludin antibody kits.

The overall structural characteristics of the occludin proteins are preserved across all species studied. Insufficient expression of tightly junction-related proteins which includes the occludin protein is a significant molecular defect that causes greater permeability of tumor-associated endothelial tight junctions that contribute to edemas in brain tumors.

Occludin is a membrane-integral protein that has an apparent molecular weight of around 65 kDa. It is found exclusively in close junctions (TJ) of selected epithelial and endothelial cell types. The protein has 5-22 amino acids (aa) in size. It includes a cytoplasmic N-terminus four transmembrane domains, as well as the long COOH-terminal domain of the cytoplasm (domain E) which contains 255 amino acids.

Occludin is believed to play an essential role in the formation and maintaining tight junctions. Differential phosphorylation in occludin at various residues can affect its interaction with other proteins involved in tight junctions like ZO-1. The phosphorylation of occludin by VEGF regulates tight junction stability as well as permeability to vascular blood.

Know All About Dopamine ELISA Kit

Dopamine is an organic chemical of the catecholamine and phenethylamine families that plays several important roles in the brain and body. Dopamine is an amine that is made by removing the carboxyl group of a molecule containing L-DOPA’s precursor chemical.

This is then synthesized in both the brain and the kidneys. Dopamine can also be synthesized in plants, and other multicellular organisms. Dopamine is a neurotransmitter in the brain. This chemical is released by neurons (nerve cells) to transmit signals to other nerve cells. You can buy dopamine ELISA kits via

Dopamine ELISA Kit is a competitive ELISA test for the Quantitative measurement of Dopamine levels in plasma, serum and cell culture supernatants. The Dopamine concentration in the samples can be measured. This ELISA kit can be used to in vitro quantify Dopamine.

Dopamine ELISA kits are assays designed to detect the neurotransmitter and hormone dopamine, also known as 3,4-dihydroxyphenethylamine. This molecule performs a variety of functions, including memory, motivation, vasoconstriction, dilation, renal function and endocrine signaling.

It is most closely associated with the brain, its pathways, and plays a role in conditions such as Parkinson’s disease, schizophrenia, attention deficit hyperactivity disorder (ADHD), and other mental disorders. It can be used to treat shock and heart failure.


Tumour Necrosis Factor alpha, also known as TNF alpha is an inflammatory cytokine generated by monocytes during severe inflammation and is in charge of a wide array of signalling events inside cells, resulting in necrosis or apoptosis.  The protein can also be crucial for immunity to disease and cancers.

These two receptors belong to the so-called TNF receptor superfamily.  The superfamily contains FAS, CD40, CD27, and RANK. The defining characteristic of those receptors is an additional cellular domain constituted of two to six repetitions of cysteine rich themes. You can know more about high-quality TNF ELISA via

Furthermore, a range of related “decoy receptors” exist which act to sequester TNF molecules, thus preventing cells from apoptosis. The crystal structures of TNF alpha, TNF beta, the extracellular domain of TNFR-1 and also the TNF beta have been characterized by crystallography.

The Quantikine Human TNF-alpha Immunoassay is a 3.5 or 4.5 hour solid phase ELISA designed to measure individual TNF-alpha in cell culture supernates, serum, and plasma.  It comprises E. coli-based recombinant human TNF-alpha and antibodies raised against this protein.  It’s been shown to accurately quantitate the recombinant element.

Results obtained with naturally occurring TNF-alpha samples showed linear curves which were parallel to the standard curves obtained using the Quantikine kit standards.  These results imply that this kit may be used to determine relative mass values for normal human TNF-alpha.  The Human Tumor Necrosis Factor alpha (Hu TNFα) ELISA quantitates Hu TNFα in human serum, plasma, buffered solution, or cell culture medium.

Why You Need An Insulin ELISA Kit?

The insulin ELISA Assay Kit is designed, developed and created for the quantitative dimension of human insulin in serum or EDTA-plasma samples. The assay uses the “sandwich” technique with chosen antibodies that bind to several epitopes of Insulin.

Assay criteria, controls and patient samples have been inserted straight to wells of a microplate that’s coated using an anti-human Insulin special antibody. Simultaneously, a horseradish peroxidase-conjugated monoclonal Insulin special antibody is added to every well. You can buy high-quality insulin ELISA kit via

Following the initial incubation period, the antibody on the wall of microtiter well catches human Insulin at the sample and also unbound proteins in each microtiter are washed off.  A “sandwich” of “anti-Insulin antibody conjugated tracer antibody” is shaped.  The unbound tracer antibody is eliminated in the following washing step.

For the discovery of the immunocomplex, the well is then incubated with a substrate solution at a timed reaction then quantified in a spectrophotometric microplate reader. The enzymatic action of the immunocomplex bound to individual Insulin on the walls of the microtiter well is directly proportional to the total amount of Insulin at the sample.

A typical curve is generated by plotting the absorbance versus the various human Insulin concentration for each standard on point-to-point or 4 parameter curve fit.  The concentration of individual Insulin in evaluation samples is determined right from this standard curve. The Insulin ELISA is a FDA registered in vitro diagnostic instrument for the quantification of human cells at a clinical setting or research lab.

Learn About Cortisol ELISA

Cortisol is the most abundant circulating steroid along with also the significant glucocorticoid secreted by the adrenal gland. Cortisol is successful in blood pressure care and in anti-inflammatory action too. It’s also involved in calcium absorption, gluconeogenesis in addition to the secretion of uric acid and pepsin.

It’s increased under-stress scenarios, physical exercise, and outside management of ACTH. Levels of cortisol levels generally may be utilized as a sign of adrenal function and the differential diagnosis of Addison’s and Cushing’s diseases in addition to adrenal hyperplasia and carcinoma. You can buy high-quality cortisol ELISA kit at

Most circulating cortisol is likely to cortisol binding globulin or transcortin and albumin. The free cortisol, which is regarded as the active portion of blood, is roughly 1 to 2 percent. From the absence of considerable quantities of these cortisol binding proteins in saliva.

Salivary cortisol is regarded as free and reveals that a diurnal rhythm with the greatest levels in the daytime and the lowest amounts at nighttime. Cortisol Enzyme Immunoassay or ELISA Kit is a competitive immunoassay specially created and validated for the quantitative measurement of salivary cortisol. It’s intended just for research use in humans and some animals.

Cortisol production has a circadian rhythm, with levels peaking in the morning and falling to the lowest values at nighttime. Levels increase independently of circadian rhythm in reaction to pressure. In blood, only around 5-10percent of cortisol is at its unbound or biologically active type. The rest of the cortisol is bound to serum proteins. Cortisol ELISA Kit is a competitive assay that may be used for quantification of cortisol in plasma, urine, and other sample matrices.
