The ExcelTaq™ 2X Q-PCR Master Mix (SYBR, ROX) is a ready-to-use reagent with all the essential components for quantitative real-time PCR (qPCR) except primers and template. The master mix features high sensitivity and high signal intensity when compared with Brand A. The ExcelTaq™ 2X Q-PCR Master Mix (SYBR, ROX) contains hot-start Taq polymerase in an optimized buffer with dsDNA specific SYBR green fluorescent dye. This master mix allows for sensitive and precise amplification, real-time tracking of the amplification process, and simultaneous quantification for targeted DNA molecules. The master mix includes ROX reference dye for normalization of each qPCR assay. With inert smart blue contrast dye, the ExcelTaq™ 2X Q-PCR Master Mix (SYBR, ROX) is ready-to-use and greatly reduces pipetting errors, while largely improving the reproducibility of the process.

Programmed Death-Ligand 1 (PD-L1), also known as CD274 or B7 Homolog 1 (B7-H1), is a transmembrane protein involved in suppressing the immune system and rendering tumor cells resistant to CD8 T cell-mediated lysis through binding of the Programmed Death-1 (PD-1) receptor. Overexpression of PD-L1 may allow cancer cells to evade the actions of the host immune system. In renal cell carcinoma, upregulation of PD-L1 has been linked to increased tumor aggressiveness and risk of death, and, in ovarian cancer, higher expression of this protein has lead to significantly poorer prognosis. PD-L1 has also been linked to systemic lupus erythematosus and cutaneous melanoma. When considered in adjunct with CD8 tumor-infiltrating lymphocyte density, expression levels of PD-L1 may be a useful predictor of multiple cancer types, including stage III non-small cell lung cancer, hormone receptor negative breast cancer, and sentinel lymph node melanoma.
With the development of molecular biology, stool, a new non-invasive sample, has been widely used in the research of animal molecular genetics, population ecology, behavioral ecology and some intestinal disease diagnosis. Stool samples includes gut microbial DNA, food residue sample DNA, and alimentary tract exfoliated cell DNA.
The primary problem encountered when using stool sample for molecular biology research is the low content of exfoliated cells in the digestive tract and a certain degree of degradation of genetic material in stool. Another issue in molecular scatology research based on PCR is the presence of a large number of inhibitors in stool that can affect Taq enzyme activity, leading to downstream detection inactivation. These inhibitors include polysaccharides, plant polysaccharides, bile acids, bile salts, bile pigments, digestive juices, mucus, etc. Therefore, selecting appropriate extraction methods to obtain high-quality DNA is the key to successful downstream detection of stool DNA.
At present, the pretreatment methods used in the laboratory, such as phenol/chloroform extraction, cetyltrimethyl bromide (CTAB) lysis, and guanidine isothiocyanate lysis, lack universality in different species, and the success rate of extracting DNA for PCR amplification is also very low. The HiPure Stool DNA Kit provided by Magen Company has opened up a new approach for DNA extraction from stool samples with good universality, high cost-effectiveness, high yield and purification. The reagent kit adopts a unique solution system and inhibitory factor adsorbent, which can efficiently remove various impurities in stool samples. The purified DNA can be directly used for PCR, quantitative PCR and other applications.
This product allows rapid and reliable isolation of high-quality genomic DNA from various stool samples. Up to 100 mg soil samples can be processed in 60 minute. The system combines the reversible nucleic acid binding properties of HiPure matrix with the speed and versatility of spin column technology to eliminate PCR inhibiting compounds such as humic acid from soil samples. Purified DNA is suitable for PCR, restriction digestion, and next-generation sequencing. There are no organic extractions thus reducing plastic waste and hands-on time to allow multiple samples to be processed in parallel.

Principle
Stool sample is homogenized and then treated in a specially formulated buffer containing detergent to lyse bacteria, yeast, and fungal samples. Humic acid, proteins, polysaccharides, and other contaminants are removed using our proprietary Absorber Solution. Binding conditions are then adjusted and the sample is applied to a DNA Mini Column. Two rapid wash steps remove trace contaminants and pure DNA is eluted in low ionic strength buffer. Purified DNA can be directly used in downstream applications without the need for further purification.
Advantages
High purity – unique adsorbent can completely remove inhibitory factors
High concentration – maximum extraction of total DNA from stool samples
High recovery – DNA can be recovered at the level of PG
Good repeatability – silica technology can obtain ideal results every time

Storage and Stability
Proteinase K and Buffer PCI should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2–8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.
