M-MLV Retro Transcriptase

Moloney Murine Leukemia Virus Reverse Transcriptase (M-MLV RT) is a RNA-dependent DNA polymerase used to generate first-strand complementary DNA (cDNA) from poly-mRNA, total RNA or viral RNA for use in downstream applications such as RT-(q)PCR or cDNA cloning. This enzyme contains several point mutations in the RNase H domain that enhances its thermostability and increases the cDNA yield of full-length transcripts (>5 kb) than wild-type M-MLV RT.

Suggested reaction conditions

Recommended use of 200 units per 20 µL reaction. Denature RNA and primers by incubating at 65-70 °C for 5 min and mix them with dNTPs, MgCl2, provided buffer (Ref.; BMVRTHC) and M-MLV Reverse Transcriptase. Incubate the mixture at 45 °C for 30 min, inactivate the enzyme at 95 °C for 2 min and proceed with the generated cDNA.

Activity unit definition

One unit incorporates 1 nmol of dTTP into acid-precipitable material in 10 minutes at 37°C using poly(A)•oligo(dT)25 as template-primer. 

Storage conditions

Once received, store the lyophilized product at Room Temperature, while buffers and MgCl2 should be stored at 4 °C or -20 °C. Once reconstituted, store M-MLV Reverse Transcriptase at -20 °C or -80 °C. Avoid multiple freeze/thaw cycles by storing multiple aliquots.

Buffer composition

This lyophilized product is provided with 1X M-MLV Reverse Transcriptase Reconstitution Buffer (ref.: RB-L3MVRTHC), 10X M-MLV Reverse Transcriptase Reaction Buffer (Ref.: BMVRTHC) and 100 mM MgCl2 (Ref.: MGCL2).

The lyophilized M-MLV Reverse Transcriptase contains 50,000 U. To obtain a final concentration of 200 U/µL, add 250 µL of reconstitution buffer (ref.: RB-L3MVRTHC) and gently pipette up and down. Aliquot into smaller volumes to avoid multiple freeze/thaw cycles.

PCR Enzymes and solutions

Polymerase chain reaction (PCR) is one of the most common techniques in molecular biology, having a wide range of applications. Conventional PCR is a qualitative technique for detection and amplification of nucleic acids. However, real time PCR, also known as quantitative PCR (qPCR), allows sensitive and specific quantification of nucleic acids. The product portfolio of Levprot includes enzymes for conventional PCR and real time PCR, but also for reverse-transcription PCR, DNA digestion and ligation reactions, as well as Master Mixes for DNA and RNA samples.

mRNA Synthesis

mRNA synthesis has gained importance since mRNA vaccines and therapeutics became relevant in biopharma. Synthesis of mRNA requires several steps from DNA template to pure mRNA, including post-translational modifications and additional components needed for mRNA synthesis. Levprot offers a product portfolio that includes products that covers all of the above.

Isotermal amplification

Isothermal nucleic acid amplification is a unique method to amplify limited amounts of DNA at constant temperature, eliminating the thermal cycling process and thus, the need of a thermocycler equipment. One of the most common isothermal amplification methods is LAMP (loop-mediated isothermal amplification), in which loop structures facilitate rounds of amplification using 4-6 primers. At Levprot we offer a Bst DNA polymerase which is uniquely useful for a variety of isothermal amplification reactions.

CLIA Enzymes

Chemiluminescent immunoassay (CLIA) is a technique that uses luminescent molecules which  emit electromagnetic radiation (i.e. producing light) triggered by a chemical reaction. This immunoassay technique is more sensitive than conventional colorimetric ELISA methods as it allows the detection of target molecules in biological samples at zeptomole scale (10-21 mol) due to chemiluminescent signal multiplication and amplification.

Blocking buffers

Blocking buffers are inert solutions of a single or a combination of proteins that bind onto surfaces of different nature. These buffers prevent non-specific interactions of antibodies or antigens to membranes or plates, reducing background interferences and increasing the signal-to-noise ratio in immunoassays.

Next generation Sequencing

Next Generation Sequencing (NGS) is a parallel sequencing tech that offers more speed and scalability and is very useful to determine the order of nucleotides in entire genomes of DNA or RNA. NGS has several enzymatic workflow steps, in which polymerases, restriction enzymes, ligases and kinases-phosphorilases have an important role.

Antigens

Antigens are foreign molecules that trigger an immune response acting against what is considered a possible external attack. Their presence makes the immune system produce antibodies against them. The production of antigens is useful for immunoassays as they allow the specific detection of antibodies (i.e. markers of disease) against an antigen.
