血红蛋白是红细胞主要组分,是一类转运蛋白:将氧气从肺部输送至全身,并把二氧化碳运回肺部。一个血红蛋白分子由 2 对多肽链(α、β 珠蛋白链)与 4 个血红素辅基组成,每个血红素含 1 个铁原子。在肺血管内氧分压 100 mmHg 的生理条件下,95%–98% 的血红蛋白与氧结合;在远离肺部、氧分压显著更低的组织中,氧气可从血红蛋白上解离释放。
为什么血红蛋白检测十分重要?血红蛋白水平高于正常值,可能由脱水、骨髓红细胞过度生成、严重肺部疾病或其他重症引起;水平低于正常值可引发贫血,诱因包括缺铁、维生素 B12 与叶酸缺乏、遗传性血红蛋白缺陷、肝硬化、红细胞破坏过多。
阿拉丁生产并供应人红细胞血红蛋白(Hb),该产品可作为指标物,用于医学研究及临床诊断试剂研发中评估贫血或红细胞增多症相关慢性出血的严重程度。
产品备注
本制剂主要成分为高铁血红蛋白(MetHb)。
Hemoglobin the main component of red blood cells, is a protein that carries oxygen away from the lungs and carbon dioxide back to the lungs. A molecule consists of 2 pairs of peptide (alpha and beta globins) chains and four heme groups, each with one atom of iron. At a normal oxygen tension of 100 mmHg in the blood vessels of the lungs, 95-98% of hemoglobin is combined with oxygen. In the tissues further from the lungs, where the oxygen tension is much lower, the oxygen readily separates from hemoglobin.
Why is testing hemoglobin so important? Higher than normal levels may result in dehydration, excess production of red blood cells in the bone marrow, severe lung disease or other severe conditions. Lower than normal levels may lead to anemia that can result in iron deficiency, B12 and folate deficiency, inherited hemoglobin defect, cirrhosis of the liver, excessive destruction of red blood cells.
Aladdin produces and supplies human RBC Hemoglobin (Hb) for use as an indicator to measure the severity of chronic bleeding in anemia or polycythemia conditions in medical research and clinical diagnostic manufacturing.
Product Note
This preparation is predominately methemoglobin.
