细胞培养用碳酸氢钠(Sodium bicarbonate, for cell culture；Sodium hydrogen carbonate for cell culture、Soda bicarbonate for cell culture)是一种呈中性至微碱性的无机盐，在空气中易受潮分解。它能维持培养基pH值，进而调控巨噬细胞中诱导型一氧化氮合酶(iNOS)的表达及一氧化氮(NO)的生成，还可逆转肿瘤微环境的酸中毒状态。碳酸氢钠应用广泛，涵盖食品、医药、化妆品等领域，主要用作缓冲剂、调味剂、消毒剂、制药原料及质子梯度调节剂，同时也是常用抗酸剂，可抑制胃肠道疾病、中和胃酸并缓解胃部不适。
