Proteinase K (Powder), 100mg

Proteinase K is a highly active serine protease (MW 28,500 Da) isolated from the fungus Tritirachium album. The enzyme exhibits broad cleavage specificity on native and denatured proteins and is widely used in the purification of native RNA and DNA from tissues or cell lines. Because the solution is tested for the absence of RNases and DNases, it is ideal for isolating PCR and RT-PCR templates. The activity of Proteinase K is increased in the presence of denaturants such as SDS (1%) and elevated temperature (50-60°C). The recommended working concentration is 50-100 μg/mL for protein removal and enzyme inactivation and up to 2 mg/mL for tissue treatment. Proteinase K products are free of detectable DNase and RNase.

TRIsure, 100 ml

TRIsure provides a simple, efficient method for the sequential isolation of total RNA, genomic DNA and proteins from a wide variety of starting materials. By combining thiocyanate compounds with phenol, TRIsure facilitates disruption of cells during homogenization and effectively inhibits DNase and RNase activity. After homogenizing the sample with TRIsure, chloroform is added and the homogenate is allowed to separate into three phases: a clear aqueous phase (upper) containing the RNA, a green colored organic phase (lower) and an interphase, containing the DNA and proteins. The RNA is extracted from the aqueous phase by isopropyl alcohol precipitation, DNA is precipitated from the organic layer with ethanol and the proteins are precipitated from the phenol-ethanol supernatant by isopropyl alcohol precipitation. The precipitated RNA, DNA, or protein is washed to remove impurities and then resuspended for use in downstream applications. TRIsure allows for highly reliable integrative analysis of the transcriptome, genome and proteome, since the RNA, DNA and proteins are derived from the same sample and the same cell population. The simplicity of the TRIsure method allows simultaneous processing of a large number of samples and can be used in a wide variety of downstream applications including expression profiling, epigenetics, genotyping, transgenic analysis and cell line characterization.

dNTP Mix, 40mM Final Conc., 20μmol, (1 x 500μl)

Highly quality dNTPs are a vital requirement for successful PCR, as the presence of contaminating impurities will result in a decrease in amplification sensitivity and product yield. Bioline ultra-pure dNTPs undergo highly stringent purification steps to give a greater than 99% purity and are tested or the absence of DNase, RNase, Protease, Nickase activity. They are then quality controlled& in a variety of applications, ensuring that they are highly suitable for the most sensitive of PCR techniques. All Bioline dNTP Mixes are supplied as an equimolar solution of ultra-pure dATP, dCTP, dGTP and dTTP as lithium salts. Lithium salts have greater resistance to repeated freezing and thawing cycles than sodium salts and remain sterile due to the bacteriostatic activity of lithium towards various microorganisms, giving greater reliability and an extended shelf life. As an ISO 13485 certified primary manufacturer of nucleotides, if your requirements for nucleotides are beyond the scope of our standard product range, Bioline can also offer custom, bulk and OEM services (custom@bioline.com).

Random Hexamer Primer, 25μg

Product Highlights Mixture of oligonucleotides -for RNA missing a polyA tail such as bacterial RNA Binds randomly -for RNA with strong secondary structure Product Description Random Hexamer Primers consist of a mixture of oligonucleotides representing all possible hexamer sequences. Random Hexamer Primers are commonly used for priming single-stranded DNA or RNA for extension by DNA polymerases or reverse transcriptases. During cDNA generation, random priming gives random coverage to all regions of the RNA to generate a cDNA pool containing various lengths of cDNA. Random priming is incapable of distinguishing between mRNA and other RNA species present in the reaction. Primer Sequence: 5´ – d (NNNNNN) –3´ N = G, A, T or C A mixture of random hexamer primers and oligo(dT) may improve the sensitivity of cDNA synthesis.

Oligo (dT) 18, 27μg

Product Highlights Long oligonucleotide -more thermostable Reverse Transcriptases perform better with longer primers Binds only to mRNA -can be used for cDNA synthesis with total RNA Product Description Oligo (dT)18 Primer is suitable for use as a primer for first strand cDNA synthesis with a reverse transcriptase. The primer hybridizes to the poly-adenylated tail found on the 3´ end of most eukaryotic mRNAs. Oligo (dT)18 ensures that the 3´ end of mRNAs are represented. Primer sequence: 5´-d (TTT TTT TTT TTT TTT TTT)-3´ A mixture of random hexamer primers and oligo(dT) may improve the sensitivity of cDNA synthesis.
