gene 611938
Species Reactivity
This assay has high sensitivity and excellent specificity for detection of CASQ2. No significant cross-reactivity or interference between CASQ2 and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between CASQ2 and all the analogues, therefore, cross reaction may still exist in some cases.
Serum, plasma, cell culture supernatants, body fluid and tissue homogenate
Assay Type
Competitive (Quantitative)
1.0 pg/mL.
Preparation and Storage
Store all reagents at 2-8 degree C.
Sample Preparation
We suggest pre-experimenting with neat (undiluted) samples, 1:2 or 1:4 dilutions. Please avoid diluting your samples more than 1:10 as it would exceed the dilution limit set for this kit. If the expected concentration of the target is beyond the detection range of the kit, please contact our technical support team
Product Note
Our ELISA Kit assays are dynamic research tools and sometimes they may be updated and improved. If the format of this assay is important to you then please request the current manual or contact our technical support team with a presales inquiry before placing an order. We will confirm the current details of the assay. We cannot guarantee the sample manual posted online is the most current manual.
Other Notes
Small volumes of CASQ2 elisa kit vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS7200165 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Calsequestrin-2 (CASQ2) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing CASQ2. The ELISA analytical biochemical technique of the MBS7200165 kit is based on CASQ2 antibody-CASQ2 antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect CASQ2 antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, CASQ2. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

Intended Uses: This CASQ2 ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Porcine CASQ2. This ELISA kit for research use only, not for therapeutic or diagnostic applications!

Principle of the Assay: CASQ2 ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-CASQ2 antibody and an CASQ2-HRP conjugate. The assay sample and buffer are incubated together with CASQ2-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the CASQ2 concentration since CASQ2 from samples and CASQ2-HRP conjugate compete for the anti-CASQ2 antibody binding site. Since the number of sites is limited, as more sites are occupied by CASQ2 from the sample, fewer sites are left to bind CASQ2-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The CASQ2 concentration in each sample is interpolated from this standard curve.

NCBI Summary for CASQ2
The protein encoded by this gene specifies the cardiac muscle family member of the calsequestrin family. Calsequestrin is localized to the sarcoplasmic reticulum in cardiac and slow skeletal muscle cells. The protein is a calcium binding protein that stores calcium for muscle function. Mutations in this gene cause stress-induced polymorphic ventricular tachycardia, also referred to as catecholaminergic polymorphic ventricular tachycardia 2 (CPVT2), a disease characterized by bidirectional ventricular tachycardia that may lead to cardiac arrest. [provided by RefSeq, Jul 2008]
UniProt Comments for CASQ2
calsequestrin 2: Calsequestrin is a high-capacity, moderate affinity, calcium-binding protein and thus acts as an internal calcium store in muscle. The release of calcium bound to calsequestrin through a calcium release channel triggers muscle contraction. The skeletal muscle isoform (CASQ1) binds around 80 Ca(2+) ions, while the cardiac isoform (CASQ2) binds approximately 60 Ca(2+) ions. Defects in CASQ2 are the cause of catecholaminergic polymorphic ventricular tachycardia type 2 (CPVT2); also known as stress-induced polymorphic ventricular tachycardia (VTSIP). CPVT2 is an autosomal recessive form of arrhythmogenic disorder characterized by stress-induced, bidirectional ventricular tachycardia that may degenerate into cardiac arrest and cause sudden death. Belongs to the calsequestrin family.
