Mycoplasma are small bacteria that are one of the most prevalent microbial contaminants of mammalian cell cultures. Mycoplasma contamination can alter the growth and metabolic characteristics of cultured cells and lead to unreliable experimental results. Mycoplasma contamination often goes unnoticed as commonly no visible changes to medium (pH or turbidity) or cellular morphology occur.

Mycoplasma contamination often goes unnoticed as commonly no visible changes to medium (pH or turbidity) or cellular morphology occur.
The CycleavePCR Mycoplasma Detection Kit enables the specific detection of Mycoplasma species from cell-culture samples using real-time PCR amplification of the Mycoplasma 16S rRNA gene. Detection of at least ten species in the genus Mycoplasma, including species commonly found in cell-culture media (M. arginini, M. hominis, M. hyorhinis, M. orale, M. salivarium, M. fermentas, M. bovis, M. arthritidis, M. pirum, and M. pneumoniae) and one species in the genus Acholeplasma (A. laidlawii) has been confirmed.
This kit enables amplification products to be detected by cycling-probe technology, a highly sensitive detection method that uses an RNA/DNA chimeric probe and RNase H. One end of the probe is labeled with a fluorescent moiety and the other end with a quencher. When intact, this probe does not emit fluorescence due to the action of the quencher. However, when it forms a hybrid with the complementary sequence of an amplification product, RNase H cleaves RNA in the chimeric probe, resulting in strong fluorescent signal emission. The amount of amplified product can be monitored by measuring the intensity of emitted fluorescence.

当然跟物种有关。
【GAPDH】或G3PDH是甘油醛-3-磷酸脱氢酶（ glyceraldehyde-3-phosphate dehydrogenase ）的英文缩写。GAPDH是参与糖酵解的一种关键酶，由4个30-40kDa的亚基组成，分子量146kDa，检测条带大约在36kDa。GAPDH基因几乎在所有组织中都高水平表达，且GAPDH 作为管家基因在同种细胞或者组织中的蛋白质表达量一般是恒定的。
【Western Blot】蛋白质印迹法（免疫印迹试验）。它是分子生物学、生物化学和免疫遗传学中常用的一种实验方法。其基本原理是通过特异性抗体对凝胶电泳处理过的细胞或生物组织样品进行着色。通过分析着色的位置和着色深度获得特定蛋白质在所分析的细胞或组织中表达情况的信息。
