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.

Norgen’s microScript microRNA cDNA Synthesis Kit is an all-in-one, ready-to-use product for the reverse transcription of microRNA from either Total RNA preparations or enriched microRNA preparations. The kit contains the 2x Reaction Mix and the microScript microRNA Enzyme Mix. The kit utilizes Norgen’s microScript Reverse Transcriptase, a mutant version of Moloney Murine Leukemia Virus (M-MuLV) Reverse Transcriptase. It has reduced RNase H activity and increased thermal stability.
The workflow of Norgen’s microScript microRNA cDNA Synthesis Kit involves a simple, single-tube set-up by the mixing of 2x Reaction Mix, Enzyme Mix and the RNA template. The reaction can then be carried out in a thermocycler. A poly (A) tail is first added to the RNA template, followed by cDNA synthesis using an adapter primer. In addition to the ease-of-use, the single-tube set-up provides superb consistency and sensitivity. The cDNA could be used in a PCR or qPCR amplification using a Universal PCR Reverse Primer and the forward primer that contains the sequence of the microRNA of interest. A single cDNA preparation could be used for PCR amplification of a number of different microRNAs. In addition, the cDNA preparation could be used for PCR or qPCR detection (using gene-specific forward and reverse primers) of mRNA or large RNA if total RNA preparation was the starting template. This could allow for parallel evaluation of expression level of microRNAs and microRNA-targets.

Mycoplasma is the smallest and simplest prokaryotic organism. There is a risk of mycoplasma contamination during cell culture, and mycoplasma contamination of cells has become a common problem worldwide.
Mycoplasma contamination may seriously affect the state of cells, change the gene expression and metabolic characteristics of cells, lead to slow cell growth, abnormal differentiation and death, and seriously affect cell function.
Bacteria, yeast or mold contamination in cell culture can be seen under an optical microscope, but mycoplasma contamination is usually not visible under an optical microscope and must be detected by specific detection methods.
Common methods for detecting mycoplasma contamination include mycoplasma isolation and culture, special biochemical tests such as ELISA and luminescence, and DNA fluorescent staining detection. Among the above detection methods, most of the operation steps are relatively cumbersome, the sensitivity is not high, the mycoplasma types cannot be distinguished, special instruments are required, or the time required is long. The qPCR method is relatively simple and convenient to operate, and the results can be obtained in 2 hours.
• Provide results in less than 2 hours.
Good negative and positive controls.
• No live mycoplasma required: The MycoSEQ Mycoplasma Detection Kit does not contain any live mycoplasma and does not require the use of live mycoplasma for validation
• Can be used with gDNA, inactivated mycoplasma, or live mycoplasma
• Can be used as an alternative to the standard 28-day culture test
• Can be used in conjunction with culture-based methods to provide preliminary results while awaiting the 28-day test results
The MycoSEQ Plus Mycoplasma Detection Kit is part of an integrated workflow for adventitious drug, impurity, and contaminant detection during biopharmaceutical manufacturing. The entire workflow includes the sample preparation kit, which provides a manual sample preparation method, which together with the qPCR analysis can provide results in 2 hours. (Please note that complex matrices may require additional upfront processing steps as described in the various available protocols.)
• Mycoplasma qPCR MIX, store at -15°C to -25°C, store at 2°C to 8°C after first use, protected from light.
• Mycoplasma Positive Control, -15°C to -25°C.
• Mycoplasma Negative Control, store at -15°C to -25°C, store at 2°C to 8°C after first use.

DuckyBio’s Mycoplasma PCR Detection Kit is a TaqMan™-based quantitative PCR (qPCR) kit for detecting mycoplasma contamination in biological materials such as cultured cells. Designed and tested using criteria often applied toward rapid mycoplasma detection in biotherapeutic manufacturing cell culture lot release, the MycoSEQ Plus kit enables results that meet or exceed guidance on sensitivity and specificity expectations as described in European Pharmacopoeia (E.P. 2.6.7, 2007), US Pharmacopoeia (US63) and Japanese Pharmacopoeia. When used with a suitable sample preparation method, the MycoSEQ Plus kit can detect less than 5 CFU/mL.
The kit is developed for RNA quantification. The RNA Quantification HS kit includes HS Dye, HS Dilution Buffer, and two RNA Standards. Simply dilute the HS Dye with the HS Dilution Buffer, add RNA sample, then read the concentration using the Qubit Fluorometer. The assay is accurate for RNA concentrations from 250 pg/µL to 100 ng/µL (Figure 1). The RNA Quantification High Sensitivity Kit has several advantages over traditional RNA quantitation such as stability, sensitivity, and contaminant tolerance.
Features
The performance of the BioDynami RNA Quantification HS kit is nearly identical to that of Thermo Fisher’s Qubit RNA HS kit (figure below).
Common contaminants such as detergents, solvents, salts, free nucleotides, or protein are well tolerated in the assay (Table 1).
