The Norgen LowRanger 100 bp DNA Ladder is prepared to ensure quality and batch-to-batch consistency. Our LowRanger contains eleven discrete fragments ranging from 100 bp to 2000 bp in 100 bp increments with a higher intensity reference band at 500 bp. This Ladder is ideal for fast running times and accurate visual determination.
Contents:
1mL of premixed DNA ladder (0.5µg/10µL) in loading buffer (10mM EDTA, 10% glycerol, 0.015% bromophenol blue, and 0.17% SDS).

LowRanger 100bp DNA Ladder (Cat# 11500) – 100 loads
Ladder Properties:
• Eleven discrete bands, ranging from 100 bp to 2000 bp
• Higher intensity band at 500 bp for easy reference.
| Fragment | Size (bp) | Mass (ng) |
| 1 | 2000 | 110 |
| 2 | 1500 | 83 |
| 3 | 1000 | 55 |
| 4 | 800 | 44 |
| 5 | 700 | 39 |
| 6 | 600 | 33 |
| 7 | 500 | 55 |
| 8 | 400 | 22 |
| 9 | 300 | 17 |
| 10 | 200 | 22 |
| 11 | 100 | 22 |
Recommended Use:
Mix thoroughly. For best results, load 10µL of DNA ladder per well. For precise mass determination with a densitometer, stain gel after electrophoresis using 0.5µg/mL ethidium bromide for 30-40 minutes. The table above shows the size and mass for each band based on 10µL ladder per well.
Storage:
Stable at room temperature. For longer term storage, -20°C is recommended.
This ladder was standardized using 10µL of DNA per lane on a 0.8 cm thick, 13 x 15 cm, 1.0% agarose gel run in TAE buffer.
This kit provides for rapid spin column isolation and purification of total RNA and genomic DNA simultaneously from a single plant sample without splitting the lysate. Norgen’s plant lysis solution is highly robust and effective over a wide range of plants including challenging samples. The total RNA and genomic DNA are both column purified in under 30 minutes. Since RNA and DNA are isolated without splitting the lysate, variability and inconsistent results are reduced. All sizes of RNA including microRNA are recovered without the need for phenol. Optional on-column DNase and RNase treatments provide flexibility to isolate DNA-free RNA or RNA-free DNA respectively. Isolated nucleic acids are of a high quality and yield, and are ready for downstream use including PCR, qPCR, RT-PCR, qRT-PCR, sequencing and more.
Background
It is often necessary to isolate total RNA and genomic DNA from a single plant sample, such as for studies of gene expression, mutant or transgenic plant characterization, and host plant-pathogen characterization. This is of great benefit when isolating RNA and DNA from precious, difficult to obtain or very small samples. Furthermore, gene expression analysis will be more reliable since the RNA and DNA are derived from the same sample, therefore eliminating inconsistent results.

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.
