Protein Expression Systems & Vectors
 |
Expression vectors and kits for cell-free, prokaryotic, yeast, bacterial, insect, lentiviral, and mammalian expression, as well as fluorescent protein vectors. High yields of high-quality proteins suitable for an array of downstream functional and structural studies can be produced using Expressway™ Cell-Free, Champion™ pET, T7 and pBAD prokaryotic, Pichia, baculovirus, T-REx™, Flp-In™, FreeStyle™, and ViraPower™ lentiviral expression systems, as well as Vivid Colors™ fluorescent protein vectors.
|
Bacterial Expression
Protein expression in E coli is simple, easy and fast while delivering high yields, making the most popular protein expression technique.
|
 |
Mammalian Expression
Constitutive and inducible mammalian expression systems are ideal choices to produce proteins with proper folding and post-translational modifications. Discover Invitrogen's wide range of mammalian expression systems for your research.
|
|
Yeast Expression
Offering advantages of E. coli (high yields, easy scale-up, etc.) and expression in a eukaryotic host (protein folding, posttranslational modifications) the Pichia system is an ideal choice.
|
|
Cell-Free (in vitro) Expression
Cell-Free expression systems produce high yields of active protein at both small and large scales in 1 hour, saving time and effort.
|
|
Insect Expression
Baculovirus expression systems are powerful and versatile systems for high-level, recombinant protein expression in insect cells.
|
|
Transfection & Selection
Effective reagents for gene delivery to introduce plasmid DNA, siRNA or RNAi duplexes, oligonucleotides, and RNA into eukaryotic cells.
|
|
Reporter Assays
| You will find vectors, antibodies, reagents and kits for expressing and detecting a variety of reporter genes including glycosidases, Chloramphenicol Acetyltransferase, green fluorescent protein (GFP), β-lactamase, as well as Lumio™ and TC-FlAsH™ technology. |
