Aminooxy-PEG3-propargyl has a alkyne group and an aminooxy group. The aminooxy group reacts with aldehydes or ketones to form a stable oxime linkages. The alkyne group can participate in copper catalyzed azide-alkyne Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.

Norgen’s CleanAll DNA/RNA Clean-Up and Concentration Micro Kit provides a rapid method for the purification, cleanup and concentration of RNA or DNA from different isolation methods or upstream applications. The kit can be used as an alternative to organic extraction and ethanol precipitation to clean up various enzymatic reactions.
The CleanAll Kit purifies RNA from phenol/guanidine-based protocols or from various upstream enzymatic reactions such as DNase treatment, labeling and in vitro transcription. Furthermore, endotoxins can be removed from previously purified RNA solutions.
The kit can be used to clean up DNA from digestions, ligations, PCR reactions, labeling reactions, DNA modification reactions and staining. The kit also provides a protocol for the rapid removal of endotoxins from previously purified DNA down to 0.1 EU/µg DNA or less.
Purify all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA (miRNA) and small interfering RNA (siRNA).
Purify all sizes of DNA, from small PCR products, native or linearized plasmids, to genomic DNA. Using an alternative protocol, even oligonucleotides and smaller DNA fragments can be purified.

Usages：
Determination of coliform and fecal coliform for multiple tube fermentation.
Principle:
Tryptone provide carbon and nitrogen sources to meet the needs of bacterial growth; sodium chloride osmotic pressure balance can be maintained; Lactose is a coliform fermentable sugars; potassium dihydrogen phosphate and dipotassium phosphate is a buffer; lauryl sodium can inhibit the growth of non-coliform bacteria.
Formulation (per liter):
Trypticase:20g
Sodium chloride: 5g
Lactose:5g
Potassium dihydrogen phosphate: 2.75g
Dipotassium hydrogen phosphate :2.75g
Sodium lauryl sulfate 0.1g
Final pH6.8 ± 0.2
How to use:
1. Suspend 35.6g of the product, adding 1 L of distilled or deionized water, heated to boiling stirring until completely dissolved, packed in a test tube with a small down tube, 121 ℃ autoclave 15min, leave to cool to room temperature, standby .
2.Sample handling and dilution.
3.Selected three consecutive dilution, each dilution was inoculated three LST broth tubes, each tube was inoculated 1mL.
4. Put the tubes in an incubator 36 ± 1 ℃ cultured for 48 ± 2h.
5. Observe the results. if all LST broth don’t pruduse gas, can be reported as negative for E. coli, if gas production then will have to make further confirmed by experiments.
Quality control:
Quality control strains were inoculated and culuture at 36 ± 1 ℃ for 24h ,results are as follows:
Bacterial Name Bacterial No. Growth Status Gassing
Escherichia coli ATCC25922 good +
Salmonella typhimurium CMCC (B) 50115 good —
Staphylococcus aureus ATCC6538 inhibited —
Storage: Store in a dark, cool and dry place, tighten the cap immediately after use. Storage period of three years.
