Saxitoxins (STXs) are naturally occurring alkaloids produced by some marine dinoflagellates and by strains of various species of freshwater cyanobacteria. Saxitoxin is one of the prevalent paralytic shellfish toxins (PSTs). It belongs to a family of potent neurotoxins with a molecular weight around 300 Da. Saxitoxin and its derivatives are alkaloids composed of a tetrahydropurine ring system with a highly polar guanidinium group. Due to their significant toxicity, saxitoxins are closely monitored in marine environments where they can accumulate in the food chain during harmful algal blooms (HABs). An action level of 800ppb, or 80ug per 100grams of shellfish, has been established.
Document
Screening of saxitoxin in shellfish samples as low as 50ppb in sample Format: 25 tests (12 tests, 12 controls) Filters, syringes, extract collection tubes, buffers Run Time: 30 Minutes
Propargyl-PEG10-NHS ester serves as a bifunctional PEG linker with a terminal propargyl that participates in click reactions with azide-bearing moieties and an NHS ester group that reacts readily and efficiently with amine-bearing molecules. The PEG10 units improve the water solubility of the molecule. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Isolate full diversity of RNA (including microRNA) without phenol
Purified RNA is ready for any application including RT-PCR, qRT-PCR, RNA-Seq, arrays and more
Cytoplasmic RNA is free of DNA and ready for direct use in RT-PCR/qRT-PCR
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
This kit provides a rapid method for the isolation and purification of both cytoplasmic and nuclear RNA from cultured animal cells and small tissue samples. The kit can be used to isolate all sizes of RNA from the cytoplasmic and nuclear RNA fractions, including all small RNA species without any requirement for phenol. Included in the kit are sufficient reagents to perform either 50 cytoplasmic RNA preparations or 25 cytoplasmic and 25 nuclear RNA preparations. Ten samples can be processed in approximately 45 minutes. This kit is also available in a 100 prep size.
Background
In certain circumstances it is desirable to be able to isolate fractionated RNA as opposed to total RNA. For example, it may be preferable to isolate only mature, cytoplasmic RNA for some studies on expression profiling. Alternatively it may be desirable to isolate nuclear RNA in order to investigate and study pre-processed (non-spliced) RNA. Furthermore, this kit can be used to isolate RNA for downstream applications where it is necessary to avoid DNA contamination, since the cytoplasmic fraction has been shown to be free of all traces of genomic DNA.
RNA Yield HeLa (1 x 106) – Cytoplasmic RNA HeLa (1 x 106) – Nuclear RNA
