Our general recommendations are as follows: Store at -20 °C (freezer) for up to six months. Store at 2-8 °C (refrigerator) for up to two weeks. Store at 20-25 °C (room temperature) for up to three days. According to J. Biol. Chem, 237, 2161-2174 (1962), cytochrome c is stable to boiling, and over an unusually wide range of pH values. However, it denatures readily at extreme pH (low or high), and in high concentrations of organic solvents, such as ethanol or acetone.

应用
在各种研究中，细胞色素 c 被用作线粒体依赖性细胞凋亡的诱导剂。细胞色素 c 中氧化位点的识别和监测可能对评估氧化应激相关病症和疾病具有重要意义。它有可能用作评估氧化损伤程度以及细胞和组织抗氧化能力的生物标志物。
细胞色素 c 适合用作磷酸盐缓冲液的成分，用于采用蓝色天然凝胶电泳（BN-PAGE）检测和评估复合物 IV 活性。它还可用于检测分离的肾脏吞噬细胞中的细胞外超氧阴离子 (ECSA)。

马的细胞色素c经过H2O2和UV 处理后的特异性位点和氧化程度已经过表征。研究表明这些位点可能可用作细胞内氧化环境的生物标记。
生化/生理作用
细胞色素c的主要身份是电子载体线粒体蛋白。在细胞内，细胞色素c能够在二价铁和三价铁之间转化，使得它称为了有效的生物电子载体，在动植物细胞内氧化中起到很重要的作用。它通常被视作呼吸作用催化剂，在呼吸底物和氧气之间形成必需的电子桥
细胞色素c被认为是凋亡途径中的重要中介体。线粒体细胞色素c释放，进入细胞质，激发细胞凋亡，通常被作为细胞凋亡过程的指示剂。

I see that you list several horse heart cytochrome c products. What are the differences, and which one should I choose?
1 answer-
Product No. C2506 is prepared with trichloroacetic acid (TCA), whereas C7752 is prepared with the milder acetic acid. The TCA method may reduce the amount of superoxide dismutase (SOD) present, but tends to cause dimerization or acid-modified structures of cytochrome c. In contrast, acetic acid preparations may have slightly higher amounts of SOD, but a lower proportion of dimeric cytochrome c. So C2506 would be recommended for enzyme activity studies that require low SOD, whereas C7752 is recommended for structural studies or binding studies, or for enzyme activity studies where possible SOD contamination is not a problem. Product No. C2867 is prepared from C2506; it is a BioUtra grade product, greater than or equal to 99% pure as determined by SDS-PAGE. It is recommended when an ultra-high purity is required. Product No. C3256 is also prepared from C7752; it is isolated by ion-exchange chromatography. This fraction shows a high rate of ascorbic acid oxidation, but low activity in a cytochrome oxidase system. Product No. C7150 is also prepared from C7752; it is suitable for use as a gel filtration molecular weight marker.
