ProteinPaintbox®

Synthetic non-Aequorea fluorescent and chromogenic proteins bring a world of color to your research.

Overview

ATUM’s synthetic fluorescent and chromogenic proteins (non-Aequorea) are an ideal source of protein coding sequences (genes) that can be easily excised using the flanking restriction sites and cloned into any other expression vector of choice. These vectors can also be used as expression vectors or as positive controls, and allow monitoring of inducible protein expression.

Fluorescent Proteins - Overview

ATUM’s synthetic non-Aequorea fluorescent proteins are intended to be used as a source of different fluorescent protein coding sequences (genes) that can be easily excised using the flanking BsaI restriction sites and cloned into any other expression vector of choice. These vectors can also be used as expression vectors (T5 promoter) or as positive controls and allow monitoring of inducible protein expression.

Chromogenic Proteins - Overview

ATUM’s chromogenic proteins are intended to be used as a source of different color protein coding sequences (genes) that can be easily excised using the flanking BsaI restriction sites and cloned into any other expression vector of choice. These vectors can also be used as expression vectors (T5 promoter) or as positive controls and allow monitoring of inducible protein expression.

Yes! The individual color names in the ProteinPaintbox derive from our 2011 Holiday publication, Nine improved monomeric fluorescent proteins from Rangifer tarandus, where the proteins were named after Santa’s reindeer (Rudolph, Donner, Comet, etc…). As the ATUM fluorescent and chromogenic proteins became available for sale, we kept the reindeer names. As we added new colors to our product line, we continued with the holiday naming theme, branching out to include a diversity of cultural winter traditions, classic holiday literature, drama, and of course, television cartoons. We hope you enjoy this naming scheme. Should you have any questions regarding the protein names or wish to suggest additional names, please email us at communications@atum.bio.

Sure, you can learn more about vector design with T5 promoter, lac operator for IPTG induction and increased protein expression in bacterial systems here.

Multiple CFPs, GFPs, etc. have been selected to cover a range of intensities. For example, FrostyCFP – 20000, CindyLouCFP – 35000, TwinkleCFP – 12000. It is also important to remember, that while optimized for each host system, these protein sequences have not been optimized for your individual project needs. By providing you with a large range of choices, you can test a variety of proteins to determine which works best for your research.

No, the Paintbox proteins need oxygen to mature, so cannot be expressed anaerobically.

The Biobrick set (3 FPs, EiraCFP, JuniperGFP and BlazeYFP) have been donated by ATUM to the BioBricks Foundation and are covered under the Biobricks licensing agreement (BLA). These belong to BioBricks, and are therefore not included in the ATUM ProteinPaintbox set.

The green/yellow FPs share only 27% homology at the amino acid level. Thus, it is fair to say that they are all unique proteins.

In the ATUM labs, we get colored colonies in 24hrs. As for how fast the maturation is, we have not done a time-course analysis. So, we cannot say if color develops in an hour or if it takes longer. Maturation time at 37°C – 24 hrs incubation is fast, 24-72 hrs is medium.

ATUM offers an antibody (anti-CometGFP, catalog #AB-01) that will detect GFP which could be used to determine the number of GFP molecules. However, we do not currently have data for this. Note, since this is a polyclonal Ab, it should be able to detect any of our GFPs.

Maturation time and intensity varies for each of the proteins.

For example, the intensity of RudolphRFP is lower than DasherGFP, while maturation time for RudolphRFP is longer than for DasherGFP. Thus at an early timepoint, you may have the appearance of excellent DasherGFP expression, while only minimal RudolphRFP expression.

We have not measured half-life.

However, we have looked at color after a week and it appears to remain stable.

These proteins should be able to express in any genetic background that will support T5 driven expression.

Yes, they should mature in minimal media induced with IPTG.
