CDX-2 is a caudal-related homeobox transcription factor that is expressed by intestinal epithelial cells. CDX-2 is a useful marker for gastrointestinal carcinoma, and for determining the origin of gastrointestinal metastatic adenocarcinoma and carcinoids. Anti-CDX-2 is used for differentiating lung and metastatic colorectal adenocarcinoma, however mucinous ovarian carcinoma also react positively with Anti-CDX-2, thereby limiting the ability to differentiate from metastatic colorectal adenocarcinoma.

Description

Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.

The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit. Details of the target and priming specificity are included in the individual handbooks above.

Introduction

Hipure viral RNA kit is suitable for purifying viral RNA from samples such as cell-free body fluid or culture medium. The kit is based on silica gel column purification technology. It requires no toxic phenol chloroform extraction and time-consuming alcohol precipitation in the extraction. The whole extraction process takes only 25 minutes. The kit is suitable for extracting viral RNA from 1-140µl cell-free fluid samples such as serum, plasma, cell-free body fluid or culture medium. The product has successfully extracted hepatitis B A/C, hepatitis C RNA, SARS and HIV. The obtained RNA can be directly used for RT-PCR, Northern hybridization and virus detection.

Principle

Hipure silica gel column is based on glass fiber filter membrane with high binding force. Under the condition of high concentration of ionizing agent (such as guanidine hydrochloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bond and electrostatic, while protein and other impurities are not adsorbed and removed. The filter membrane adsorbed with nucleic acid is washed to remove the residual protein and salt. Finally, the nucleic acid adsorbed on the filter membrane can be washed out with low salt buffer (such as buffer TE) or water. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.

The sample is homogenized and lysed in the lysate, and RNA is released into the lysate. The high concentration of guanidine isothiocyanate contained in the lysate denatured and inactivated endogenous or exogenous RNase, while RNA is protected from degradation. The lysate is centrifuged to remove insoluble impurities. After adding ethanol to adjust the binding conditions, it is transferred to the column for filtration. RNA is adsorbed on the membrane of the column, while protein is removed without adsorption. The column is washed with buffer VHB to remove protein and other impurities, washed with buffer RW2 to remove salt. Finally the RNA is eluted by RNase free water. The eluted RNA can be directly used in RT-PCR, Northern blot, poly-A purification, in vitro translation, etc.

Advantages

• Fast – several samples can be extracted in 20 minutes by column method
• High quality – high purity total RNA can be directly used in various sensitive downstream applications
• Safe – no phenol chloroform extraction required
• Sensitive – RNA can be recovered at the level of PG
• High yield – carrier RNA contained in the product maximize the recovery of trace nucleic acid

Storage and Stability

Carrier RNA 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 theseconditions

Introduction

HiPure PCR Pure Mini Kit uses proprietary chemistry and HiPure technology to recover DNA Fragments between 70bp-30kbp with yields exceeding 85%. DNA is suitable for ligations, PCR, sequencing, restriction digestion, or various labeling reactions. In addition, this kit can be also used to recover DNA directly from enzymatic reactions such as PCR and enzyme digestion reactions.

Compared with the gel purification kit, this product uses guanidine hydrochloride mediated adsorption, which have better A260/A230 ratio.

Specifications

Principle

The HiPure system uses a simple bind-wash-elute procedure. Gel slices are dissolved in a buffer containing a pH indicator, allowing easy determination of the optimal pH for DNA binding, and the mixture is applied to the column. Nucleic acids adsorb to the silica-gel membrane in the high-salt conditions provided by the buffer. Impurities are washed away and pure DNA is eluted with a small volume of low-salt buffer provided or water, ready to use in subsequent applications.

Advantages

• High recovery efficiency – ≥85% DNA recovery
• Fast – isolation can be completed in 10 minutes by column gel method

Kit Contents

Storage and Stability

The Kit should be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. If any precipitates form in the buffers, warm at 37℃ to dissolve.
