血紅蛋白是紅細(xì)胞的主要成分，是其具有紅色顏色的原因。它在紅細(xì)胞中的正常濃度為34％.血紅蛋白是一種帶有α和β鏈的球狀蛋白，其分別含有141和146個(gè)氨基酸。它以四聚體的形式存在，每個(gè)單體都帶有由鐵元素所構(gòu)成的血紅素的雜環(huán)卟啉環(huán).

牛血中的血紅蛋白已被用于：
? 在脊髓勻漿中利用Darbkin′檢測(cè)、四極離子淌度飛行時(shí)間質(zhì)譜用于定量腦實(shí)質(zhì)性內(nèi)出血和實(shí)質(zhì)性出血的標(biāo)準(zhǔn)曲線生成
? 在結(jié)晶研究中生成分子印跡聚合物（MIP）以模擬高分子量聚乙二醇（PEG）
α-彈性蛋白的溶解度已被應(yīng)用于彈性蛋白模擬生物材料的構(gòu)建。

Hemoglobin is the major component of red blood cells, and is responsible for their red color. Its normal concentration in erythrocytes is 34%.Hemoglobin is a globular protein with α and β chains with each 141 and 146 amino acids, respectively. It exists as a tetramer with each monomer having heterocyclic porphyrin ring with iron constituting the heme.
Hemoglobin from bovine blood has been used in:
? standard curve generation for the quantification intraparenchymal hemorrhage and parenchymal hemorrhage in spinal cord homogenate using Drabkin′s assay, Quadrupole-Ion Mobility-Time-of-Flight mass spectrometery 
?  the generation of molecularly imprinted polymers (MIPs) to mimic high molecular-weight polyethylene glycol (PEG) in crystallization studies
The solubility of α-elastin has been applied to construction of elastin-mimetic biomaterials.
