Rho1D4, also called "1D4" is an affinity tag consisting of nine amino acids (T-E-T-S-Q-V-A-P-A). The tag is preferrably added to the C-Terminus of a protein of interest. Agarose Resins and magnetic beads coupled with the matching Rho1D4-antibody are able to purify proteins that are tagged with Rho1D4. Rho1D4 protein purification assays combine the incredible high specificity of other antibody based protein purification with an high protein yield. For more information regarding Rho1D4 we have written this guide to provide you with all necessary information.

Rho1D4 protein purification in detail

Purifies protein with high specificity and yield
PureCube resins are produced under strict quality guidelines and each batch undergoes quality checks to ensure that the loaded matrix has a high protein capacity. Combined with the specificity of the antibody-epitope interaction, a purification protocol optimized for the target protein can generate elution fractions with exceptionally high yields. Figure 1 shows a purification run for chemokine receptor 4 (CXCR4). The tagged protein was expressed in E. coli, solubilized with Fos-Choline®-14 and purified on a column containing PureCube Rho1D4 Agarose beads. Using the rho1D4 peptide as eluent, the 4 elution fractions contained a total recoved protein concentration of 0.8, 1.0, 0.85 and 0.6 mg/mL. A western blot shows CXCR4 at approximately 65 kDa and 35 kDa. These bands represent dimers and monomers of the 39.7 kDa membrane protein. Separation of monomers and dimers, as well as removal of the eluent peptide, can be done with size-exclusion chromatography.

Pure and active membrane proteins
Purification results for membrane proteins purification like this can not be archived by using more common resins like Ni-NTA. Therefore Rho1D4 is your way of choice here.
