PEG3-(Amino-Tri-(Propargyl-PEG2-ethoxymethyl)-methane)-(Amino-Tri-(carboxyethoxymethyl)-methane) is reactive with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The terminal carboxylic acid groups can react with primary amino groups in the presence of activators (e.g. HATU) to form a stable amide bond.

Ki-67 is a nuclear, non-histone protein that is expressed only during active phases of the cell cycle (G1, S, G2 and M), but not in the resting phases (G0 and G1 early phase). Although the antigen has also been associated with ribosomal RNA transcription, it is strongly linked to cell proliferation and has thus been indicated as an effective marker in grading the proliferation rate of tumors, including those of the brain, breast, cervix, and prostate.
TruScript Reverse Transcriptase is Available in Three Convenient Formats:
1. TruScript Reverse Transcriptase Kit (Cat.#54440)
This kit contains 5X RT Buffer and a vial of TruScript Enzyme Mix (200 units/µL). This enzyme can be used for reverse-transcription reactions with any user-supplied primers.
2. TruScript First Strand cDNA Synthesis Kit (Cat.#54420)
This is an all-in-one, ready-to-use product for simple set-up of reverse transcription of total RNA (both poly A- or non-poly A-containing transcripts).
The kit contains the 2x Reaction Mix and the TruScript Enzyme Mix. The 2x Reaction Mix contains a blend of buffer, nucleotides and primers (oligo dT and random hexamers) for effective cDNA synthesis from total RNA transcripts.
3. TruScript First Strand cDNA Synthesis Kit for mRNA (Cat.#54400)
This is an all-in-one, ready-to-use product for simple set-up of reverse transcription of messenger RNA (poly A-containing transcripts).
The kit contains the 2x Reaction Mix and the TruScript Enzyme Mix. The 2x Reaction Mix contains a blend of buffer, nucleotides and oligo dT primer for the effective cDNA synthesis from total RNA transcripts or enriched mRNA sample.
