Vitamin B12, also called cobalamin, is a water-soluble vitamin that is involved in the metabolism of every cell of the human body: it is a cofactor in DNA synthesis, and in both fatty acid and amino acid metabolism. It is particularly important in the normal functioning of the nervous system via its role in the synthesis of myelin, and in the maturation of developing red blood cells in the bone marrow.
This kit is a product based on indirect-competitive ELISA, which is fast, easy, accurate and sensitive compared with common instrumental analysis.

RevTaq RT-PCR DNA polymerase is an engineered, extremely thermostable reverse transcriptase and combined DNA polymerase, obtained through directed, artificial evolution.
RevTaq RT-PCR DNA polymerase can be used similarly to Tth DNA polymerase also for reverse transcription, but does not require the addition of Mn2+ for RT-PCR, which simplifies assay setup and possible sample processing.
– half-life at 95°C of >40 min.
– fast start function due to a hotstart aptamer formulation which prevents unspecific amplification at lower temperatures (<57°C)
– facilitates “zero-step” RT-PCRs directly from RNA templates (without an isothermal reverse transcription step), as reverse transcription takes place simultaneously with DNA amplification during the cycled PCR elongation step.
– allows reverse transcription reactions at high temperatures, thus minimizing the problems encountered with strong secondary structures in RNA that melt at elevated temperatures.
– RevTaq RT-PCR DNA polymerase is the pure, reverse transcription active enzyme ingredient of our Volcano3G® RT-PCR Master Mixes
Please note: Due to the thermostable nature of the enzyme, it is recommended to design very high melting primers and probes (>65°C). See more details in FAQ.

[PS1000] FluoroStain™ Protein Fluorescent Staining Dye (Red, 1,000X), 1 ml

Product Info
Description
The FluoroStain™ Protein Fluorescent Staining Dye (Red, 1000×) is designed to substitute the common Coomassie Blue protein staining method, offering greater sensitivity and ease of operation. Unlike Coomassie Blue stain, the FluoroStain Protein Fluorescent Staining Dye binds to protein with high specificity, making destaining process an option rather than a requirement. With further reduction of background signals via destaining process, the FluoroStain™ is capable of achieving detection level parallel to silver staining without specialized imaging equipment, making it one of the most sensitive dyes available. In addition to its remarkable sensitivity, the FluoroStain™ Protein Fluorescent Staining Dye (Red, 1000×) brings a more reliable and safer user experience, since the stained gel can be visualized with blue-light illumination, avoiding the risk of skin/ eye damage caused by UV light. For best result, we suggest using B-BOX™ Blue Light LED epi-illuminator to visualize and analyze the gel stained with FluoroStain Protein Fluorescent Staining Dye (Red, 1000×). The FluoroStain™ Protein Fluorescent Staining Dye is compatible to the analysis of mass spectra, i.e. LC-MS/MS, MALDI-TOF, etc.
Spectral Characteristics
When it is bound with bovine serum albumin (BSA), the fluorescent emission of FluoroStain Protein Fluorescent Staining Dye can be excited by UV and blue light sources, with excitation peaks around 369 and 517 nm and emission at 605 nm. In absence of BSA, FluoroStain Protein Fluorescent Staining Dye shows ignorable fluorescence as compared with protein-bound form, therefore giving a clear background for photographic analysis.
These spectral characteristics made this fluorescent dye compatible with a wide variety of gel reading facilities, including UV/ blue light epi- and transilluminator, argon laser and mercury-arc lamp excitation gel scanners.
Storage
Protected from light -20°C for 24 months
