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.

The FastRunner DNA Ladder is prepared to ensure quality and batch-to-batch consistency. This Ladder contains eight discrete fragments ranging from 50 bp to 2000 bp with a higher intensity reference band at 500 bp. This Ladder is ideal for quick sizing of PCR products and restriction digests.
Contents
1mL of premixed DNA ladder (0.5µg/10µL) in loading buffer (10mM EDTA, 10% glycerol, 0.015% bromophenol blue, and 0.17% SDS).

FastRunner DNA Ladder (Cat# 12800) – 100 loads
Ladder Properties:
• Eight discrete bands, ranging from 50 bp to 2000 bp
• Higher intensity band at 500 bp for easy reference
| Fragment | Size (bp) | Mass (ng) |
| 1 | 2000 | 104 |
| 2 | 1500 | 88 |
| 3 | 1000 | 68 |
| 4 | 750 | 59 |

| 6 | 300 | 28 |
| 7 | 150 | 35 |
| 8 | 50 | 25 |
Recommended Use:
Mix thoroughly. For best results, load 10µL of DNA ladder per well. For precise mass determination with a densitometer, stain gel after electrophoresis using 0.5µg/mL ethidium bromide for 30-40 minutes. The table above shows the size and mass for each band based on 10µL ladder per well.
Storage:
Stable at room temperature. For longer term storage, -20°C is recommended.
This ladder was standardized using 10µL of DNA per lane on a 0.8 cm thick, 13 x 15 cm, 1.0% agarose gel run in TAE buffer.
