Human Asialoglycoprotein Receptor 2 (ASGR2) 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 ASGR2. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody preparation specific to ASGR2. 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 ASGR2, 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 ASGR2 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

Mediates the endocytosis of plasma glycoproteins to which the terminal sialic acid residue on their complex carbohydrate moieties has been removed. The receptor recognizes terminal galactose and N-acetylgalactosamine units. After ligand binding to the receptor, the resulting complex is internalized and transported to a sorting organelle, where receptor and ligand are disassociated. The receptor then returns to the cell membrane surface.

Performance Characteristics

REPEATABILITY

Intra-assay Precision (Precision within an assay): 3 samples with low, middle, and high-level ASGR2 were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle, and high-level ASGR2 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 0.049ng/mL.
ASSAY RANGE 0.156-10ng/mL
SPECIFICITY This assay has high sensitivity and excellent specificity for the detection of ASGR2.
No significant cross-reactivity or interference between ASGR2 and analogs was observed.
Note:
Limited by current skills and knowledge, it is impossible to perform all possible cross-reactivity detection tests between ASGR2 and all analogs, therefore, cross reactivity may still exist.
