AccuBand™ 100 bp DNA marker II is composed of 6 individual DNA fragments, presenting 2k, 1k, 750, 500, 250 and 100 bp sharp bands respectively. This product contains 1 enhanced band (750 bp) for easy identification of bands. AccuBand™ 100 bp DNA marker II is ready-to-use, containing loading buffer with tracking dyes of dual colors (orange and cyan). To improve the faint visibility of low molecular weight bands frequently occurred in use of conventional DNA markers, AccuBand™ 100 bp DNA marker II provides sufficient amount of DNA for 250 and 100 bp fragments, and thus ensuring clear observation of all DNA bands ranging from 100 bp to 2k bp, either in agarose gel or in polyacrylamide gel electrophoresis.

Description
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.
Features of MycoSEQ Mycoplasma Detection Kit
• 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.)

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 BK virus is a member of the polyomavirus family. BK viral infections are typically asymptomatic in healthy individuals, however very mild symptoms may appear including mild respiratory infections and fever. Once an individual has been infected the virus disseminates to the kidneys and the urinary tract where it remains for the lifetime of the individual. Infections with BK virus in immunocompromised or immunosupressed patients are much more severe and may involve renal dysfunction. In fact, in kidney transplant patients the immunosupressive drugs required for the transplant may allow the virus to replicate within the graft, resulting in a disease called BK virus nephropathy (BKVN). It is thought that 1-10% of renal transplant patients progress to BK virus nephropathy (BKVN) and up to 80% of these patients are reported to have lost their grafts. The onset of nephritis can occur as early as several days post-transplant to as late as 5 years. The mode of transmission of the virus is not clear, however it has been suggested that BKV may be transmitted through respiratory fluids or urine, since infected individuals periodically excrete virus in the urine. This virus can be diagnosed by BKV blood & urine testing, in addition to carrying out a biopsy in the kidneys. PCR techniques are now widely used to identify the virus.

Storage Conditions and Product Stability All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
Propargyl-PEG6-acid comprises propargyl and carboxylic acid functional groups. The acid group reacts with primary amines in the presence of activators (e.g. EDC, or HATU).The propargyl group reacts with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The molecule has good solubility in aqueous environment. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
