Biotin-PEG2-alkyne is a short PEG linker featuring a biotin group and a terminal alkyne. Biotin is useful for affinity-based applications such as pull-down assays while terminal alkynes are used in copper (I) click chemistry with azides.

HL-dsDNase is especially developed to remove contaminating genomic DNA from RNA preparations. Figure 1 shows that HL-dsDNase can reduce 50 ng of human gDNA to levels non-detectable by qPCR. In figure 2, a human total RNA sample was treated with HL-dsDNase and analysed on the Bio-Rad Experion™ System. The results indicate that HL-dsDNase has minimal impact on RNA quality and quantity.
HL-dsDNase is an engineered version of dsDNase that is rapidly and completely inactivated by incubation for 5 minutes at 58°C with 1 mM DTT at pH 8.0 or above. Chemical inactivation in downstream compatible RT or PCR buffers allows milder heat inactivation and, in some cases, skipping heat inactivation altogether. This makes HL-dsDNase very useful for removal of DNA from RNA preparations since the enzyme may be inactivated using various strategies with reduced risk of auto-degradation of RNA in the presence of magnesium, making HL-dsDNase an ideal enzyme when working with small volumens of RNA.
HL-dsDNase is also an excellent choice for removal of unwanted external DNA from samples prior to analysis of nucleic acids protected by biological membranes, e.g., bacteria, viruses, and sperm. Especially if using downstream analysis methods that might be affected by host cell DNA, as metagenomic sequencing and STR-profiling. The easy inactivation of HL-dsDNase makes it a fast and efficient alternative to methods as differential extraction, where sample material is often lost.

This product uses an improved salt precipitation purification method to provide a safe and economical solution for High Weight genomic DNA extraction from blood samples, tissue samples, cultured cells, oral swabs, bacteria, and other samples. The extraction does not require the use of toxic phenol chloroform or any expensive reagents, making it the most economical reagent kit for nucleic acid extraction at present. This kit has no limit onthe amount of sample used and can flexibly adjust various amounts of samples. The obtained DNA can be directly used for experiments such as PCR, enzyme digestion, Southern hybridization, and the Third-generation sequencing.
Principles
SolPure DNA Kits is an improved salt precipitation purification method. (Blood samples are lysed in red blood cell lysis buffer to remove red blood cells, and white blood cells are collected by centrifugation.) After lysis, DNA is released into the lysis buffer. RNA is removed by RNASE A. High salt solution is added to precipitate proteins and impurities. Centrifuge to remove precipitate and obtain supernatant containing only DNA. Add isopropanol to precipitate and recover DNA. Wash with 70% ethanol to remove salt, and finally add Buffer TE to dissolve DNA.

RNase A and Proteinase K should be stored at 2–8°C upon arrival. However, short-term storage (up to 4 weeks) at room temperature (15–25°C) does not affect its performance. The remaining kit components can be stored dry at room temperature (15–25°C) and are stable for at least18 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.

Sulfo DBCO-PEG4-Maleimide is a water-soluble click chemistry reagent with a maleimide group and a DBCO moiety. The hydrophilic PEG spacer arm improves solubility in aqueous buffers. Maleimide group specifically and efficiently reacts with thiols to form stable thioether bonds. The low mass weight will add minimal spacer to modified molecules and will enable simple and efficient incorporation of DBCO moiety onto cysteine-containing peptides or other thiol-containing biomolecules. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
