Invitrogen — Reagents and Kits for DNA/RNA, Cloning, and Protein Workflows

Invitrogen is Thermo Fisher’s portfolio for everyday molecular biology and protein workflows—built around trusted names such as Lipofectamine™ transfection, SuperScript™ reverse transcription, Dynabeads™ magnetic separation, TRIzol™ extraction reagents, and TOPO™ cloning. The focus is practical: consistent results, clean documentation, and components that fit together across steps.

Across discovery labs and QC groups, Invitrogen products help you move from sample to answer with fewer hand-offs: transfect and express, extract and purify, clone and verify, stain and quantify. Classic staples—Platinum™ Taq for PCR, SYBR™ Safe DNA gel stain, and the Invitrogen Qubit™ fluorometers—round out day-to-day analysis without changing your established protocols.

Core Product Categories

These categories reflect commonly paired steps in molecular workflows. Use them to navigate from nucleic-acid preparation to analysis, or to standardize routine methods across teams. Each category lists representative Invitrogen products that are widely used and well-documented in the portfolio (examples, not an exhaustive list).

• Transfection

  • Lipofectamine™ family for DNA/RNA and hard-to-transfect cells (e.g., Lipofectamine 3000; Lipofectamine 2000).

  • 

     

• Reverse Transcription / cDNA Synthesis

  • SuperScript™ (e.g., SuperScript IV, SuperScript III) for efficient, robust RT.

  • 

• RNA/DNA/Protein Extraction

  • TRIzol™ reagent for total RNA or simultaneous RNA, DNA, and protein isolation.

  • 

• Cloning

  • TOPO™ TA Cloning™ Kits for fast, 5-minute insertion of Taq-amplified products.

  • 

• PCR Enzymes

  • Platinum™ Taq DNA Polymerase (antibody-mediated hot start) for specific amplification.

  • 

• Magnetic Separation

  • Dynabeads™ (e.g., Protein G) for cell, protein, and nucleic-acid workflows; technology originated with Dynal and is now produced by Invitrogen.

  • 

• DNA Stains for Gels

  • SYBR™ Safe DNA Gel Stain as a sensitive, less-hazardous alternative to EtBr.

  • 

• Quantitation Instruments

  • Invitrogen Qubit™ 4 (and Qubit Flex) fluorometers for fast, specific DNA/RNA/protein measurements.

  • 

In addition to Invitrogen, Thermo Fisher’s classic brands include Applied Biosystems (qPCR instruments, TaqMan™ assays, master mixes) and Gibco (cell-culture media, sera, and supplements). Explore these pages if your workflow extends into real-time quantification or cell culture.
