Hemoglobin is a tetramer (which contains 4 subunit proteins) called hemoglobin A, consisting of two alpha and two beta subunits non-covalently bound, each made of 141 and 146 amino acid residues, respectively. The subunits are structurally similar and about the same size. Each subunit has a molecular weight of ~17kD, for a total molecular weight of the tetramer of ~68kD. Source: Human Erythrocytes Applications: Suitable for use as calibrators and controls in Lateral Flow and Turbidimetry Latex assays. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for 6 months after receipt at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
Reinheit:
Prepared by separating erythrocytes from plasma by centrifugation. The plasma is siphoned off and ether is added to the erythrocyte paste causing the cells to lyse. A second centrifugation removes the cell walls resulting in a clear red solution of hemoglobin.
Formulierung:
Supplied as a liquid in PBS, 0.25% BSA, 0.09% sodium azide.
