Precision

Intra-assay Precision (Precision within an assay):Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.

Intra-Assay CV: 4.3%

Inter-assay Precision (Precision between assays):Three samples of known concentration were tested in five separate assays to assess inter-assay precision.

Inter-Assay CV: 7.4%

Recovery
Recovery was determined by spiking various levels of 2,3-Bisphosphoglycerate into serum and plasma.

Linearity
The linearity of the kit was assayed by testing samples spiked with appropriate concentration of 2,3-Bisphosphoglycerate and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

General Annotation


Sub Unit:
N/A


Function:
2,3-Bisphosphoglyceric acid (2,3-Bisphosphoglycerate or 2,3-BPG, also known as 2,3-diphosphoglycerate or 2,3-DPG) is a three-carbon isomer of the glycolytic intermediate 1,3-bisphosphoglyceric acid (1,3-BPG). 2,3-BPG is present in human red blood cells (RBC; erythrocyte) at approximately 5 mmol/L. It binds with greater affinity to deoxygenated hemoglobin (e.g. when the red cell is near respiring tissue) than it does to oxygenated hemoglobin (e.g., in the lungs) due to spatial changes: 2,3-BPG (whose size is estimated at about 9 angstroms) fits in the deoxygenated hemoglobin configuration (11 angstroms), but not as well in the oxygenated (5 angstroms). It interacts with deoxygenated hemoglobin beta subunits by decreasing their affinity for oxygen, so it allosterically promotes the release of the remaining oxygen molecules bound to the hemoglobin, thus enhancing the ability of RBCs to release oxygen near tissues that need it most. 2,3-BPG is thus an allosteric effector.
