RNA/DNA/Protein Purification Plus Kit
This kit provides a rapid method for the high throughput isolation and purification of total RNA, DNA and proteins sequentially from a single sample of cultured animal cells, small tissue samples, blood, bacteria, or yeast. The kit employs two columns: 1) for gDNA purification and 2) for RNA purification utilizing Norgen’s resin columns (superior for the binding of all RNA sizes including miRNA). The proteins are also purified on the second column after RNA elution. The proteins are eluted in buffer and are ready for downstream application without any further clean up required. The proteins can be quantified directly, used in western blots, ELISA or mass spectrometry. This kit provides a rapid spin-column method for the isolation and purification of total RNA, genomic DNA and proteins sequentially from a single sample of cultured animal cells, small tissue samples, blood, bacteria, yeast, fungi or plants.
RNA/DNA/Protein Purification Plus Micro Kit
This kit provides a rapid spin-column method for the isolation and purification of total RNA, DNA and proteins sequentially from a single sample of cultured animal cells, small tissue samples, microdissected samples including LCM, stem cells, sorted cells, and CTC. The total RNA, genomic DNA and proteins are all column purified in less than 30 minutes. The RNA and DNA can be eluted in as little as 20 µL while the protein can be eluted in as little as 50 µL. This kit provides the same performance as if the samples were isolated from dedicated kits.
RNA/DNA/Protein Purification 96-Well Plus Kit
The kit employs two plates: 1) for DNA purification and 2) for RNA purification utilizing Norgen’s resin (superior for the binding of all RNA sizes including miRNA). Please see the protocol schematic below.

| Application examples: | Assay of microbial pullulanase preparations. Measurement of limit-dextrinase in malt extracts. |
| Method recognition: | Novel method |
PullG6 assay for the measurement of pullulanase employs a water soluble defined substrate, namely 4,6-O-benzylidene-4-nitrophenyl-63-α-D-maltotriosyl-maltotriose (BPNPG3G3), coupled with the ancillary enzymes α-glucosidase and β-glucosidase. Upon hydrolysis of the substrate at the 1,6-α-linkage by pullulanase or limit-dextrinase, the released 4-nitrophenyl-β-maltotrioside is immediately hydrolysed to glucose and 4-nitrophenol by the concerted action of the α-glucosidase and β-glucosidase enzymes in the reagent mixture. The reaction is terminated and phenolate ions are developed by addition of dilute alkali. The absorbance is read at 400 nm and the value obtained correlates directly with pullulanase activity.
