Salt (KCl) concentration

at lower salt concentrations, whereas many primer pairs producing short amplification products worked better at higher salt concentrations. This is illustrated in the three figures below in which there is a realtive shift in the intensity of the products

Bile Salt-Activated Lipase

The presence of a redundant lipolytic system of bile salt-activated lipase (BAL) and pancreatic lipase results in the concerted action of these lipolytic enzymes during intestinal dietary fat digestion processes (1 ). Because of its wide

盐腺 salt gland

　　盐腺 salt gland （ 1）为海产软骨鱼类、爬行类和鸟类的 NaCl分泌腺，在软骨鱼类有开口于直肠的直肠腺，在爬行类和鸟类有，开口于鼻腔的鼻腺，龟的开口于眼窝的泪腺，已变为盐腺。盐腺的分泌液主要含 NaCl，排出比海水浓度还要大的溶液。分泌细胞中有大量的线粒体，与哺乳类的肾小管细胞的构造非常相似。 Na－ K－ ATP 酶活性高。用海水养鸭时，其盐腺可发达增大数倍。 　　（ 2）指树苗（主要是叶）向表面分泌盐类的构造。亦称钙腺。盐腺的构造因种属而异
