β-N-Acetylglucosaminidase Assay Kit



β-N-Acetylglucosaminidase (NAG) is a lysosomal enzyme involved in a variety of biological processes such as the degradation of glycoproteins and glycolipids, cell proliferation, and signal transduction. NAG is found in many tissues in the body, but due to its high molecular weight, it can not be filtered through the glomerular membrane. For this reason, in the presence of tubular damage or a glomerular lesion, urinary NAG activity increases. Elevated NAG levels in urine are an early indication of renal damage, such as injury due to diabetes mellitus, inflammation, nephritic syndrome, urinary tract infection, and more. Various forms of cancer have been associated with increased levels of NAG in serum. Genetically inherited lipid storage disorders, such as Tay-Sachs and Sandhoff disease, arise from deficiencies of the enzyme. BioAssay Systems non-radioactive, colorimetric NAG assay is based on the cleavage of p-nitrophenol from a synthetic substrate. p-Nitrophenol becomes intensely colored after addition of the stop reagent. The increase in absorbance at 405 nm after addition of the stop reagent is directly proportional to the enzyme activity. https://www.bioassaysys.com/N-Acetylglucosaminidase-Assay-Kit.html

Amylase Assay Kit – all the critical points of interest

Image
The amylase Assay Kit is utilized as a bit of interest to perform colorimetric territory. It can be utilized as a bit of an expansive combination of tests that might be recorded as underneath: •              Cell culture supernatant •              Urine •              Serum •              Plasma •              Other common liquids •              Tissue Extracts •              Cell culture media It takes 40 minutes to lead one test with this specific unit. To the degree species reactivity is concerned it responds with mice, individuals, and rats. It is relied upon to work with warm blooded animal things as well. This colorimetric measure pack is utilized to see an amylase action by procedure for a response that uses a couple of means. An amylase divider ought to disengage the substrate known as ethylidene-pNP-G7. This is done recollecting a definitive goal to make parts that are more diminutive in nature. It is a-glucosidase that as time goes on changes

AMPK Phosphorylation Assay Kit

Image
The 5-AMP-activated protein kinase (AMPK) is a key sensor of intracellular energy balance. AMPK is activated in response to an increase in the AMP/ATP ratio which can be caused by a number of factors such as muscle contraction, starvation, or hypoxia. AMPK is a heterotrimeric protein complex comprising of α - (63 kDa), β - (38 kDa) and γ - (38 kDa) subunits. For each subunit, isoforms have been identified ( α 1, α 2, β - 1, β - 2, γ 1, γ 2, γ 3) which theoretically allow the formation of 12 different proteins. The α -subunit contains a serine/threonine kinase domain and the regulatory subunits contain binding sites for AMP and ATP and for glycogen. AMPK is activated by phosphorylation on Thr-172 within the catalytic domain. AMP binding results in a 2 to 5-fold increase in AMPK activity compared to the basal level. Binding of AMP to the α -subunit causes allosteric activation of the kinase and induces a conformational change in the kinase domain that protects AMPK from dephosphoryla

Assay Solutions: A basic idea

Image
The science industry is always in need of highly effective assay solutions. Assaying is a process – rather a chemical analysis- where metals are tested for the presence or strength of components that are already present in them. Needless to say, assaying is highly important for scientific researches. A few basic ideas about assay kits Based on the researchers’ needs (or rather the demands of the scientific research itself), researchers can choose from among several assay kits. A few are mentioned below: Ø   ATPAssay Kit   Ø   CaspaseAssay Kit Ø   CholesterolAssay Kit Ø   CytotoxicityAssay Kit Ø   FattyAcid Assay Kit  Ø   Glucoseassay Kit  Ø   GlutathionePeroxidase Kit Ø   KinaseAssay Kit What you need to do However, researchers are required taking an important stand when it comes to selecting a company offering assay solutions. Now, with the increasing demand for assay kits in scientific research, the number of companies offering these solution
