The 50 bp DNA Ladder is prepared to ensure quality and batch-to-batch consistency. This Ladder contains ten discrete fragments ranging from 50 bp to 500 bp with a higher intensity reference band at 250 bp. This Ladder is ideal for quick sizing of PCR products
Contents 1mL of premixed DNA ladder (0.5µg/10µL) in loading buffer (10mM EDTA, 10% glycerol, 0.015% bromophenol blue, and 0.17% SDS).
Ladder Properties: • Ten discrete bands, ranging from 50 bp to 500 bp • Higher intensity band at 250 bp for easy reference

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.

Overview
Extract high quality & quantity total RNA including miRNA
No phenol step required; isolate all RNA in one fraction
Bind & elute all RNA irrespective of size or GC content, without bias
Very sensitive & linear down to a few cells without the need for carrier RNA
Isolate from a wide variety of specimens
Purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services
Available in a variety of formats to suit your needs
Purification is based on spin column chromatography that uses Norgen’s resin separation matrix
These kits are suitable for the isolation of total RNA from a range of samples including cells, bacteria, yeast, virus and bodily fluids including plasma/serum, blood, saliva, CSF and more. Extract high quality and purity RNA with excellent RIN values and A260/A280 suitable for downstream applications including qRT-PCR, RT-PCR, microarrays, NGS and more. These kits purify all sizes of RNA from large mRNA, lncRNA down to microRNA (miRNA) in the same fraction without the requirement of phenol. Isolate all RNA sequences at an equal rate irrespective of size. Moreover, when the RNA sequences are small (e.g. miRNA), the column binds small RNAs regardless of their GC content.
Total RNA Purification 96-Well Kit (High Throughput and High Throughput Deep Well)
This 96-well kit provides a rapid method for the high-throughput isolation and purification of total RNA in 30 minutes using vacuum manifold, plate centrifuge, or liquid handlers with vacuum capabilities. Total RNA can be isolated from a broad range of sample sources including cultured cells, tissues, blood, serum, plasma, bacteria, yeast, fungi, and viruses.
* for isolating total RNA from larger amounts of tissue, please use Norgen’s Animal Tissue RNA Purification Kit (Cat# 25700)
Storage Conditions and Product Stability All solutions should be kept tightly sealed and stored at room temperature. These kits are stable for 2 years after the date of shipment.
Attogene’s Microcystin Test Kit (Rapid – Recreational Water) can be used to detect microcystins in liquid samples; highly sensitive, rapid, robust screening kit for algae toxins microcystins and nodularins.
The most frequently reported cyanobacterial toxins are the hepatotoxic microcystins (MCs). MCs are peptides with a molecular weight ranging from 900 to 1,100 Da. They consist of seven amino acids of which the two terminal amino acids of the linear peptide are condensed to form a cyclic compound.
A tiered notification system which takes different actions based on different numeric thresholds for microcytin-LR concentrations in recreational waters has been developed. This is guidance that allows states to take various actions—such as posting information about harmful algal blooms (HABs), issuing a recreational public health advisory, or temporarily closing recreational waters through a no contact advisory—depending on the severity of the bloom event.
Microcystin-LR
Informational sign postings about HABs at recreational waters: < 6 μg/L Recreational public health advisory: 6 μg/L Elevated recreational public health advisory (e.g. no contact): 20 μg/L
