Lets Know About Calnexin Antibody

Calnexin is responsible for the assembly of histocompatibility molecules in murine class I. Calnexin, a calcium-binding protein embedded within the ER membrane, retains newly synthesized glycoproteins in the ER to ensure quality control and proper folding. 

Calnexin's specificity for a particular subset of glycoproteins can be determined by the presence of a lectin, which binds an intermediate early oligosaccharide on the folding glycoprotein. You can know more about Calnexin antibody via


Calnexin (also known as IP90 or p88), is an integral membrane protein that measures approximately 90 kDa in the endoplasmic reticulum. Many resident ER proteins serve as molecular chaperones, and help in the proper folding and assembly of polypeptides into multisubunit proteins. 

Calnexin is associated with the major histocompatibility complicated (MHC) class 1 heavy chains, partial complexes, and the B cell membrane immunoglobulin but not with complete receptor complexes. Calnexin, a chaperone, is known to retain incompletely or incorrectly folded proteins in ER. 

Lys-AspGlu-Leu (KDEL), or a closely related sequence is found at the carboxyterminus of soluble ER resident protein such as GRP78, GRP94, and protein disulfide Iomerase. Calnexin is an integral membrane ER resident protein that lacks the KDEL sequence, but has positively charged cytosolic residues that allow for ER retention. 

Calnexin has a large ER luminal region (461 amino acid), a transmembrane segment (22.2 amino acids) and a cytoplasmic trail (89 amino acids).


Scientific Details About TNF ELISA

The TNF-α or Tumor Necrosis Factor Alpha ELISA Kit is a α- or alpha protein sometimes glycoprotein present in blood. Transcription related growth factors and stimulating factors are complex subunits of proteins involved in cell differentiation.

Complex subunit associated factors are involved in hybridoma growth, Eosinohils, eritroid proliferation and derived from promotor binding stimulating subunits on the DNA binding complex. Enzyme-Linked Immunosorbent Assays, Human proteins and human recombinants are used in quantitate human TNF ELISA kits and to produce anti-human mono and polyclonal antibodies.

Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples. Tumor necrosis factor is a cell signaling protein (cytokine) involved in systemic inflammation and is one of the cytokines that make up the acute phase reaction.

It is produced chiefly by activated macrophages, although it can be produced by many other cell types such as CD4+ lymphocytes, NK cells, neutrophils, mast cells, eosinophils, and neurons. TNF ELISA kit allows the detection and quantification of endogenous levels of natural or recombinant Human TNF alpha in plasma, serum, and lysates.

The Human TNF Alpha (TNF-α) ELISA employs the quantitative sandwich enzyme immunoassay technique. A monoclonal antibody specific for TNF-α has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any TNF-α present is bound by the immobilized antibody. Tumor necrosis factor-alpha is a cytokine involved in systemic inflammation.


Things To Know About ELISA Kits

Enzyme-linked immunosorbent assay is a biochemical process in immunology that's mostly used for determining the presence of an antibody or antigen in a sample. Among the ELISA test kits for cancer is Prostatic Acid Phosphatase (PAP), which can be used for measuring the prostatic acid phosphatase (PAP) in the plasma and serum of an individual.

For many years, the medicated ELISA kits were used as a diagnostic tool in plant pathology and medicine. It has test kits that are utilized for cancer, fertility, thyroid, steroid, autoimmune diseases, infectious diseases and allergy, parasitology, and diabetes assays.

The components of the kit are intended for use as an integral component only. Consequently, the components from several lots have to be separated.

The Diagnostic Automation Enzyme Immunoassay is also test equipment for cancer. It's specially designed for the quantitative apprehension of prostate-specific antigen in the human plasma.

Another case of the test equipment is the Human Allergen Specific ELISA Assay, which can be utilized to qualitative and quantitate the allergen-specific individual Immunoglobulin E. The complete IgE of this specimen is arranged before completing allergen-specific assays.

The Growth Hormone, another sort of test kit is used for analyzing the fertility of a woman. It determines the human growth hormone concentration inside the human serum.

Also, there are test kits for communicable diseases and among them is the Bordetella pertussis, which is meant to be utilized for determining the particular IgA immunoglobulins against the Bordetella pertussis from the plasma and serum.
