Definitions
- the present invention relates to compounds (markers) in particular for the detection of phosphoric acid esters, the compounds comprising a chelating agent, a central atom and a fluorescent dye.
- Phosphoric acid esters are vital components of biological systems and components of a large number of biochemical compounds. They play an important role particularly in the function and regulation of cellular processes, where they e.g. occur as intermediate products in numerous metabolic processes.
- Biologically important phosphoric acid esters are e.g. Adenosine mono-, di- and triphosphates, lecithins, kephalins, phospholipids, nucleotides and coenzymes.
- the phosphorylation and dephosphorylation of proteins by protein kinases or phosphatases also play a particularly large role in regulation processes. The detection of phosphorylated molecules or the analysis of the phosphorylation state of biomolecules is therefore of great importance in biological research.
- c) comprises at least one dye bound to the chelating agent (s).
- Multidentate chelating agents such as iminodiacetic acid (IDA) and their derivatives, nitrilotriacetic acid and their derivatives, polyoxycarboxylic acids and their derivatives, polyamines and their derivatives or ethylenediamine acetic acid and their derivatives are preferably used.
- a protein purification system is also sold by QIAGEN.
- the system can be used to isolate proteins and peptides that have been labeled with six successive histidine residues. These residues have a high affinity for immobilized nickel ions, which in turn are chelated to nitrilotriacetic acid resins (Ni-NTA).
- Ni-NTA nitrilotriacetic acid resins
- a major disadvantage of this system is that the proteins and peptides must be labeled with the histidine residues.
- QIAGEN also offers Ni-NTA conjugates with antibodies, peroxidase, alkaline phosphatase and horseradish peroxidase.
- the at least one central atom or ion coordinated with the chelating agent is preferably a metal atom or ion, in particular a transition metal atom or ion such as iron and / or nickel, but can also represent one (or more) other group (s) that have lonely electron pairs or electron gaps.
- Fe 3+ is preferably used.
- the compounds according to the invention can comprise one or more bridging ligands.
- the dyes used according to the invention are preferably chemically bound to the chelating agent, but can also be associated with the chelating agent in other ways.
- the term dyes used here also includes pigments and other chromophoric groups and their educts which, for example, only become chromophores after the reaction with the chelating agent (s).
- Dyes such as xanthene dyes such as fluorescent dyes, in particular fluorescein and its salts and derivatives such as fluorescein isothiocyanate can be used.
- a preferred compound according to the invention is the iron (III) complex of N-iminodiacetic acid ethyl-N '-fluoresceinylthiourea.
- the compounds according to the invention can be prepared by a process in which at least one of the chelating agents listed above is reacted with at least one of the dyes mentioned above under suitable conditions and then at least one of the central atoms or ions defined above is added under suitable conditions.
- the following diagram shows a preferred embodiment of the process according to the invention:
- An aminoethyliminodiacetic acid (1) is reacted with fluorescein isothiocyanate (2) to give the compound (3).
- the chelate (4) ie a compound according to the present invention, can be precipitated.
- the compounds according to the invention can be used in an assay, preferably for the detection and / or for the separation of compounds containing at least some phosphoric acid ester groups.
- an assay preferably for the detection and / or for the separation of compounds containing at least some phosphoric acid ester groups.
- amino acids or proteins can be analyzed proteins or peptides and isolated (physically separated), have the same or nearly identical sequences, said peptides or proteins or respective groups of which groups a different number of organophosphate ⁇ have.
- the expression "almost identical sequences” preferably means that the sequences are not more than one amino acid per 20 amino acids, more preferably per 30 amino acids, even more preferably per 40 amino acids and still more ker preferably differentiate per 100 amino acids of the total frequency.
- Proteins or peptides are analyzed and / or separated that differ only in the number of their phosphoric acid ester groups. You can do this as follows:
- two types of beads were produced, each carrying an octapeptide sequence and differing only in that one sequence contains a serine phosphate and the other contains an unmodified serine.
- the two populations were examined by measurements in a FACS device (line scanner and sorter). The result is shown in the following figure, which shows that the fluorescent labeling of the sequence with the serine phosphate is significantly stronger; the two types of beads are approximately baseline separated.
- proteins or peptides can be analyzed and / or separated (also physically separated), which differ both in the number of their phosphoric acid ester groups and in their sequences. You can do this as follows:
- proteins or peptides can be analyzed and / or separated (also physically separated) which have an identical or similar number of phosphoric acid ester groups but different differences, such as different peptide or protein sequences.
- the physical sorting (separation) can take place in cell sorters.
- a similar number of phosphoric acid ester groups preferably means that the number of phosphoric acid ester groups of the different peptides or proteins by a maximum of 10%, preferably by a maximum of 5%, even more preferably by a maximum of 2% and most preferably by less than 1%, based on the number of phosphoric acid ester groups of the compound with most Phosphoric acid ester groups, the difference being at least one phosphoric acid ester group.
- sequences preferably means that the sequences differ by at least 1 amino acid per 19 amino acids of the total sequence.
- Beads are mixed with the corresponding unphosphorylated sequences (e.g. X-X-X-X-S-A-A and A-A-R-R-S-A-A) and incubated with PKA (protein kinase) and phosphorylated.
- PKA protein kinase
- the beads with the highest fluorescence were selected with a FACS sorter (two populations, R2 and R3, as shown in Figure 3).
- the pool sequence analysis of the collected beads shows that the beads at position X mainly carry arginine (R), which corresponds to the known motif of this protein kinase.
- the method is therefore suitable for identifying consensus motifs for a large number of, for example identified but little characterized, protein kinases.
- the compounds according to the invention can also be used in many other assays, for example in the analysis and separation of proteins and peptides containing phosphoric acid ester groups in protein gels or on blots, in capillary electrophoresis and gel electrophoresis:
- ovalbumin as a phosphorylated protein could be intensively marked with the fluorescein-IDA-iron complex according to the invention and detected with a corresponding detector ( Figure 5).
- the unphosphorylated control protein glucoce oxidase showed only a weak background fluorescence (Fig. 6).
- This area of application enables the efficient control of biological phosphorylation processes in in vitro and in vivo assays.
- Proteins can be separated by gel electrophoresis. The individual proteins can then be blotted onto a carrier membrane. On such blots (nitrocellulose), phosphorylated proteins were specifically labeled with the fluorescein-IDA-iron complex.
- the compounds according to the invention can be used for the detection of recombinant peptides or proteins with His tags (eg an additional sequence of 6 histidine residues), with transition metals other than Fe as the central atom or ion, such as for example, Cu, Ni, Co and / or Zn atoms or ions can be used.
- His tags eg an additional sequence of 6 histidine residues
- transition metals other than Fe such as for example, Cu, Ni, Co and / or Zn atoms or ions
- the present invention is e.g. B. enables easy quantification and separation of proteins and peptides because a stoichiometric, temporally stable quantification of the fluorescent group takes place. Another advantage arises from the reversible character of the color, which can be reversed by adding strong chelating agents (EDTA) or changing the pH.
- EDTA strong chelating agents
