说明

氰钴胺，也称为维生素B12，是一种水溶性维生素。
在ELISA的分析步骤期间，在测定缓冲液中加入氰钴胺素，以确保在分析之前所有的转钴胺素都被钴胺素饱和。氰基巴胺还用于检查其对体内mPer1和mPer2表达的影响。

氰胺在大脑和神经系统的功能中发挥作用。它也参与造血。维生素B12缺乏导致巨幼细胞性贫血。它还与导致脊髓退化的不可逆神经系统崩溃有关。
氰钴胺是指一组化学相关的含钴分子，参与细胞过程，如DNA合成、脂肪酸合成、能量生产和调节。氰钴胺素与其他B族维生素硫胺素（B1）和吡哆醇（B6）一起阻断脊髓神经节压迫（CCD）或坐骨神经松脱结扎（CCI）引起的神经性疼痛大鼠的热痛觉过敏。它能促进氯仿的厌氧生物降解。

一般描述

Cyanocobalamin, also referred to as Vitamin B₁₂, is a water soluble vitamin.

应用

Cyanocobalamin was added in the assay buffer during the analysis step of ELISA for ensuring that all transcobalamin was saturated with cobalamin before analysis. Cyanocobalamin was also used for examining its impact on the expression of mPer1 and mPer2 in vivo.

生化/生理作用

Cyanocobalamin plays a role in functioning of brain and nervous system. It is also involved in hematopoiesis. Vitamin B₁₂ deficiency leads to megaloblastic anemia. It is also associated with irreversible nervous system breakdown leading to spinal cord degeneration.

Cyanocobalamin refers to a group of chemically-related cobalt containing molecules involved in cell processes such as DNA synthesis, fatty acid synthesis, energy production and regulation. Cyanocobalamin along with other B vitamins thiamine (B1) and pyridoxine (B6) blocks the thermal hyperalgesia in rats with neuropathic pain caused by spinal ganglia compression (CCD) or loose ligation of the sciatic nerve (CCI). It can stimulate the anaerobic biodegradation of chloroform.
