Description

Microcystin are a class of hepatotoxins produced by blue-green algae such as Microcystis aeruginosa.  Microcystin-LR is the most common of the over 50 different congeners. Cyanobacteria can produce microcystin in large quantities during an algae bloom which then pose a major threat.

This kit can be used for quantitative test of Microcystin in liquid samples such as water, wastewater, algal cultures, and solid samples such as fish.

Overview

• No need for staining and destaining of denaturing gels since Norgen’s loading buffer contains ethidium bromide
• Highly stable
• Nine bands from 200 bases to 4000 bases
• Convenient lyophilized format provides better product stability

The Norgen 1 kb RNA Ladder is a set of RNA transcripts derived from recombinant DNA templates. This ladder is suitable for precise sizing of a wide range of RNA molecules using native or denaturing agarose gels, and can be visualized under UV.

Contents: 
• 2 vials of lyophilized RNA ladder (25 loads each)
• 1x loading buffer: 33.3% formamide, 11.7% formaldehyde, 0.012% bromophenol blue, 0.05mM EDTA, 0.012% ethidium bromide, and 0.7x MOPS solution
• 2x loading buffer

Specifications:
• Nine discrete bands, ranging from 200 to 4,000 bases
• Higher intensity band at 1,000 bases for easy reference

Contents:
• 2 vials of lyophilized RNA ladder (25 loads each)
• 1x loading buffer: 33.3% formamide, 11.7% formaldehyde, 0.012% bromophenol blue, 0.05mM EDTA, 0.012% ethidium bromide, and 0.7x MOPS solution
• 2x loading buffer

Instructions:
To reconstitute the lyophilized RNA ladder, add 250 µL of 1x loading buffer to each 25 loads vial and vortex gently.
Heat at 80°C for 10 minutes. Incubate on ice for 1 min. Load 10 µL on a 1-2% gel. For optimal results, use Norgen 2x loading buffer with each RNA sample. No need for staining and destaining of denaturing gels since Norgen’s loading buffer contains ethidium bromide.

Store at -20°C.
