PEG13-bis(Amino-Tri-(Propargyl-PEG2-ethoxymethyl)-methane) is large molecule with two sets of three terminal alkynes joined together by a large PEG linker. The alkynes are most frequently used in copper click chemistry with azides. The PEG linkers as well as numerous amide bonds provide high aqueous solubility to this compound, which may alter ADME of this compound.

The Small RNA Library Prep Kit for Illumina consists of all the reagents and components required to generate small RNA libraries to be used for next-generation sequencing on an Illumina platform. All molecular reagents including adaptors, primers, enzyme mixes and buffers are provided. A purification module is also provided for rapid purification of nucleic acid products generated at various steps of the workflow. The purification module utilizes Norgen’s patent resin technology which enhances recovery of desired library intermediates or final products. The library prep workflow could be used for different forms of input including purified total RNA or enriched small RNA, as well as RNA from low content inputs such as plasma, serum and urine.

Sample type purification kit guide
The 16S V2-V3 Library Preparation Kit for Illumina consists of the reagents and components required for library preparation of the 16S V2-V3 amplicon libraries to be used for next-generation sequencing on Illumina platforms. All molecular reagents including primers, enzyme mixes, indexes, and buffers are provided. Instructions for PCR clean up with the AMPure XP Magnetic Beads (supplied by customer) are also included for rapid purification of nucleic acid products generated at two steps of the workflow. The library prep workflow could be used for purified DNA inputs from different sources including stool, soil, water, saliva, plant, urine, skin swab, vaginal swab, cheek swab, nasal swab, plasma/serum, tongue swab, gum swab, and others.
The 16S V2-V3 Library Preparation Kit for Illumina has a streamlined procedure that reduces the handling time such that the library prep procedure can be completed in approximately 4 hours (see diagram below). Input DNA is first subjected to targeted PCR to amplify the V2-V3 region of the DNA encoding 16S rRNA. The post-PCR reaction is then cleaned up using AMPure XP beads. Dual index primers are then added using a limited-cycle PCR. The indexed amplicons flanked by 5′ and 3′ barcoded adaptors are then cleaned using AMPure XP beads. The libraries are then ready for quantification, pooling and sequencing.
