DBCO-PEG36-TFP ester is an amine-reactive, labeling reagent used to modify proteins, antibodies, and other amine-containing biopolymers. The hydrophilic PEG spacer arm provides a long and flexible connection that minimizes steric hindrance involved with ligation to complementary azide-containing molecules. The TFP ester is less susceptible to undergo hydrolysis compared to the NHS ester. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Alkyne-PEG2-iodide is a crosslinker containing a propargyl group and an iodine group. The propargyl group can form triazole linkage with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry reactions. Iodine (I) is a very good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research use only.

Norgen’s Plasma/Serum Circulating DNA Purification Kits (Slurry Format) provide efficient methods for the purification of fragmented free-circulating DNA from human plasma or serum. The kit is able to isolate all sizes of circulating DNA. The slurry format provides an advantage over other available kits in that it does not require extension tubes for the purification of free-circulating DNA from large sample volumes. DNA can be isolated from either fresh or frozen samples using this kit. The kit will also isolate viral and bacterial DNA from plasma/serum. Typical yields of purified free-circulating DNA will vary depending on the input sample (1-100ng/mL circulating DNA in human plasma), with more concentrated samples tending to yield more free-circulating nucleic acids. The purified, inhibitor-free plasma/serum free-circulating DNA is eluted in an elution solution that is compatible with PCR, qPCR, methylation-sensitive PCR and Southern Blot analysis.
Plasma/Serum Circulating DNA Purification Mini Kit (Slurry Format)
Norgen’s Plasma/Serum Circulating DNA Purification Mini Kit (Slurry Format) provides a fast, reliable and simple procedure for isolating circulating DNA from various amounts of plasma/serum ranging from 50 μL to 400 μL. Preparation time for a single sample is less than 30 minutes.
Plasma/Serum Circulating DNA Purification Midi Kit (Slurry Format)
Norgen’s Plasma/Serum Circulating DNA Purification Midi Kit (Slurry Format) provides a fast, reliable and simple procedure for isolating circulating DNA from various amounts of plasma/serum ranging from 400 μL to 2 mL. Preparation time for a single sample is less than 45 minutes.
Plasma/Serum Circulating DNA Purification Maxi Kit (Slurry Format)
Norgen’s Plasma/Serum Circulating DNA Purification Maxi Kit (Slurry Format) provides a fast, reliable and simple procedure for isolating circulating DNA from various amounts of plasma/serum ranging from 2 mL to 10 mL. Preparation time for a single sample is less than 45 minutes.

Norgen’s FFPE RNA Purification Kits provide a rapid method for the isolation and purification of total RNA (including microRNA) from formalin-fixed paraffin-embedded (FFPE) tissue samples in as little as 1 hour. Using formalin to fix tissues leads to crosslinking of the RNA and proteins, and the process of embedding the tissue samples can also lead to fragmentation of the RNA over time. Norgen’s FFPE RNA Purification Kits provide conditions that allow for the partial reversing of the formalin modifications, resulting in a high quality and yield of RNA. These kits are able to purify all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA (miRNA) and small interfering RNA (siRNA), depending on the age of the FFPE tissue as fragmentation of the RNA is known to occur over time. The RNA is preferentially purified from other cellular components without the use of phenol or chloroform.
FFPE RNA Purification Kit (Spin Column)
Maximum loading volume of 650 μL per column, and a maximum binding capacity of 50 μg per column.
FFPE RNA Purification 96-Well Kit (High Throughput)
Purification is based on 96-well column chromatography using Norgen’s proprietary resin as the separation matrix. Purification can be performed using either a vacuum manifold or centrifugation. Maximum loading volume of 400 μL per well, and a maximum binding capacity of 50 μg per well.
