BCR-522 bovine blood lysate (hemoglobin) standard

Hemoglobin (Hb) is a colored protein containing two alpha and two beta globin chains, with four heme groups surrounded by an iron atom and a porphyrin ring. Its basic function is to deliver oxygen in the form of O2 to tissues. This is achieved through the ability of iron (II) to reversibly bind with lung molecular oxygen and release it into the muscles of the body. Therefore, hemoglobin usually exists in the oxygenated state (Hb02) in arterial blood and in reduced form in venous blood. When exposed to air, it is easily re oxidized.

The measurement of hemoglobin concentration in blood is a fundamental test in laboratory medicine for disease diagnosis and management, personal healthcare, and population health epidemiological research. This is a basic examination in blood transfusion, which can determine the needs of the recipient and protect the donor. The importance of reliable and accurate measurement of hemoglobin cannot be overemphasized.

Given the importance of reliable hemoglobin testing, the European Commission has agreed to sponsor this project under its measurement and testing program, primarily to provide measurement standards for use by member states and to make them available to the World Health Organization (in collaboration with ICSH) to ensure that national authoritiesContinuously obtaining international standards.

To be ready for use, the following steps need to be performed:

Before opening the sealed ampoule, it must be allowed to equilibrate at room temperature for at least one hour. After ensuring that the contents are completely inside the ampoule, break the top of the buckle. Add the required amount into the spectrometer tube and directly read the absorbance at 540nm. The width of the slit used should be ≤ 2 nm. The absorbance at 750 nm should be less than 0.003. The absorbance ratio (A540/A504) at 540 and 504 nm should be between 1.59 and 1.63. If the material in the ampoule is sealed tightly and stored at+4 ° C before use, it can be used for up to 8 hours, but must be discarded at the end of the workday. Do not freeze or thaw. We have taken care to ensure that the certification value is as close as possible to the 'true' value at the time of customer arrival. We handle it in accordance with good laboratory practices.
