Product Information

Description

The Luna Cell Ready Probe One-Step RT-qPCR Kit provides all the necessary components for direct, probe-based RNA detection and quantitation, bypassing the need for RNA extraction and purification. The Luna Cell Ready Probe One-Step RT-qPCR Kit contains two modules: 1) the Luna Cell Ready Lysis Module (NEB #E3032S) and 2) the Luna Universal Probe One-Step RT-qPCR Kit (NEB #E3006L).

Cell cultures are often analyzed for gene expression or treatment responses as a proxy for a living organism. Traditionally, RNA is extracted and purified from treated cells via column-based or chemical methods. Coordinating the actions of DNase I and the Luna Cell Ready Protease, the Luna Cell Ready Lysis Module offers a simple alternative workflow resulting in effective cell lysis, RNA release, and genomic DNA removal simultaneously in a 15-minute protocol. The Lysis Module includes a unique Luna Cell Ready RNA Protection Reagent that maintains RNA integrity during cell lysis. The lysis capacity spans 10 -100,000 cells in a 50 µl lysis reaction. Up to 2 µl of lysate (equivalent to RNA from 0.2 - 4,000 cells) can be transferred into 20 µl downstream RT-qPCR reactions. Similar to other Luna products, the lysis buffer includes an inert blue tracking dye for visual assistance throughout the workflow.

The Luna Universal Probe One-Step RT-qPCR Kit is compatible with probe-based real-time quantitation of target RNA sequences via multiple fluorescence channels of most real-time instruments. In the Luna Universal Probe One-Step RT-qPCR Kit, Hot Start Taq DNA polymerase is combined with a novel Luna WarmStart Reverse Transcriptase, allowing dual control of enzyme activity via reversible, aptamer-based inhibition. The Luna Universal Probe One-Step RT-qPCR Kit can detect and quantitate RNA transcripts (via a singleplex or multiplex reaction) in the cell lysate prepared directly from the Luna Cell Ready Lysis Module.

This table lists cells lines that are compatible with the Luna Cell Ready Lysis Module. It includes results seen using a 5-log dilution series (100,000 - 10 cells per 50 µl lysis reaction) and subsequent detection of 1 µl of lysate in a 20 µl one-step RT-qPCR reaction. For each cell line, linear results are indicated in the final column. In addition, some insect cell lines have been tested and are compatible.

Figure 1: Luna Cell Ready One-Step RT-qPCR Workflow



The Luna Cell Ready One-Step RT-qPCR Kit provides all the necessary components for direct RNA detection and quantitation from cultured cells (up to 100,000 cells per 50 µl lysis reaction). By coordinating the actions of DNase I and the Luna Cell Ready Protease, the Luna Cell Ready Lysis Module offers a simple workflow resulting in effective cell lysis, RNA release and genomic DNA removal simultaneously in a 15-minute protocol. Up to 2 µl lysate (equivalent to RNA from 0.2 - 4,000 cells) can be transferred into 20 µl downstream RT-qPCR reactions.


Figure 2: The Luna Cell Ready Probe One-Step RT-qPCR Kit offers sensitive and accurate quantitation of RNA directly from cell lysates across 5-log cell inputs.



Serial dilutions of HeLa cells (100,000 - 10) were lysed in 50 µl Luna Cell Ready lysis reactions (NEB #E3032) using standard reaction conditions (10 min lysis at 37°C, 5 min inactivation at 25°C). Genes of interest were then quantitated using the Luna Universal Probe One-Step RT-qPCR Kit (NEB #E3006) using 1 μl of cell lysate as input (equal to 0.2 - 2,000 cells in a 20 µl RT-qPCR reaction), with duplicate reactions at each input concentration. Results for β-actin (Texas Red) and GAPDH (FAM), two abundant targets and RPL32 (HEX), a less abundant target, in multiplex (A), and singleplex reactions (B) are shown. Efficiency (E) and linearity (R2) are shown for each experiment. (C) Cq overlay of multiplex and singleplex of all 3 targets demonstrates compatibility of these results.


Figure 3: The Luna Cell Ready Probe One-Step RT-qPCR Kit offers reliable and precise RNA quantitation comparable to purified RNA across 5-log cell inputs.


Serial dilutions of A549 cells (100,000 - 10) were lysed in 50 µl Luna Cell Ready lysis reactions (NEB #E3032) using standard reaction conditions (10 min lysis at 37°C, 5 min inactivation at 25°C). Alternatively, RNA was purified using a column-based RNA extraction kit. A. Genes of interest were then quantitated using the Luna Universal Probe One-Step RT-qPCR Kit (NEB #E3006) with 1 μl of cell lysate (closed circles, left) or purified RNA (open circles, right) as input (equal to 0.2 – 2,000 cells in a 20 µl RT-qPCR reaction), with duplicate reactions at each input concentration. Detection of β-actin, an abundant target, and ARF3 and Tubulin, two less abundant targets, is shown across 5-logs of cell inputs. Efficiency (E) for each target is shown at the lower left corners of each panel.


Figure 4: The Luna Cell Ready Probe One-Step RT-qPCR Kit outperforms commercially available cell lysis One-Step RT-qPCR kits with respect to both efficiency and sensitivity.


Serial dilutions of A549 cells (100,000 - 10) were lysed in 50 µl Luna Cell Ready lysis reactions (NEB #E3032) using standard reaction conditions. Alternatively, the same amount of cells were lysed with commercially available kits from Bio-Rad (SingleShot™ Probes One-Step Kit for Cell Lysis and RT-qPCR, #172-5070), Qiagen (FastLane Cell Probe Kit, #216413) and Thermo Fisher (Cells-to-CT 1-Step TaqMan Kit, A25603) following manufacturer-recommended protocols. Genes of interest were then quantitated using the One-Step RT-qPCR module from each kit with 1 μl of cell lysate as input (equal to 0.2 -2,000 cells in a 20 µl RT-qPCR reaction), with duplicate reactions at each input concentration. Amplification of β-actin (Tye), GAPDH (FAM), and RPL32 (Cy5) in multiplex assays across 5-logs of cell inputs are shown for all kits. To standardize results, approximately 10% (Tye), 5% (FAM), 15% (Cy5) total fluorescence was set as a threshold for each kit. Efficiency (E) and the Cq of the highest and lowest input are shown.
