Human Activin A Receptor Type II A (ACVR2A) ELISA Kit

Due to the possibility of mismatching between antigens from other origin and antibodies used in our kits (e.g., antibody targets conformational epitope rather than linear epitope), some native or recombinant proteins from other manufacturers may not be recognized by our products.

Principle of the Assay

The microtiter plate provided in this kit has been pre-coated with an antibody specific to ACVR2A. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to ACVR2A. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After the TMB substrate solution is added, only those wells that contain ACVR2A, biotin-conjugated antibody, and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution, and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of ACVR2A in the samples is then determined by comparing the O.D. of the samples to the standard curve.


For Use with serum, plasma, and cell culture supernatants. For Research Use Only. Not for use in diagnostic procedures.

Target Information

On ligand binding, forms a receptor complex consisting of two type II and two type I transmembrane serine/threonine kinases. Type II receptors phosphorylate and activate type I receptors which autophosphorylate, then bind and activate SMAD transcriptional regulators. Receptor for activin A, activin B and inhibin A (PubMed:17911401). Mediates induction of adipogenesis by GDF6 (By similarity).

Performance Characteristics

REPEATABILITY

Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level ACVR2A were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle, and high-level ACVR2A were tested on 3 different plates, with 8 replicates in each plate.
CV(%) = SD/meanX100

Intra-Assay: CV<10%
Inter-Assay: CV<12%

SENSITIVITY The minimum detectable dose was 0.068ng/mL.
ASSAY RANGE 0.156-10ng/mL
SPECIFICITY This assay has high sensitivity and excellent specificity for the detection of ACVR2A.
No significant cross-reactivity or interference between ACVR2A and analogs was observed.
Note:
Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between ACVR2A and all analogs, therefore, cross reactivity may still exist.
