Definitions
- the present invention relates to new packaging for photosensitive dyes and a new method of packaging fluorochromatic reagents for cytometry.
- Flow cytometry is a very specific cell analysis technique used for decades. This technique involves at least one fluorochrome.
- the main fluorochromes used in cytometry are fluorescein isothiocyanate (FITC), phycoerythrin (PE), allophycocyanin (APC), PercP, tandems phycoerythrin-cyanine 5 (PC5), phycoerythrin-cyanine 7 (PC7) and phycoerythrin-texas red (ECD or PETR).
- FITC fluorescein isothiocyanate
- PE phycoerythrin
- APC allophycocyanin
- PercP PercP
- PC5 phycoerythrin-cyanine 5
- PC7 phycoerythrin-cyanine 7
- ECD or PETR phycoerythrin-texas red
- the tandems PC5, PC7, ECD use the principle of transfer of energy, i.e. the laser of the cytometer excites the molecule in the area spectral of phycoerythrin which restores the energy absorbed to the molecule acceptor (cyanine 5, cyanine 7 or Texas red) which will return it itself in radiative form at its emission wavelength.
- the laser of the cytometer excites the molecule in the area spectral of phycoerythrin which restores the energy absorbed to the molecule acceptor (cyanine 5, cyanine 7 or Texas red) which will return it itself in radiative form at its emission wavelength.
- Tandem dyes nevertheless absorb light throughout spectral zone and particularly in the visible zone (400-800 nm) and the Applicant has realized that these fluorochromes, alone or in tandem, were subject to significant degradation during their conservation.
- tandem phycoerythrin-allophycocyanin has been described for some time 20 years (Glazer et al. Biophys. J. (1983) 83, 383-386 and the tandems phycoerythrin-cyanine 5 for almost 10 years Lanier et al. Methods (1991) Vol 2 N ° 3 192-199. Since then, this kind of product has been marketed in bottles of brown or amber glass by BECTON DICKINSON Companies, PHARMINGEN, DAKO, IQP, or CALTAG.
- the invention is based on the use of bottles opaque to radiation bright tandem exciters, i.e. between 200 and 900 nm and more particularly between 400 and 800 nm.
- the present request relates to packaging.
- Fluorochrome sensitive to visible light means a fluorochrome whose structure is degraded by emission at the indicated wavelengths, by example fluorescein isothiocyanate (FITC), phycoerythrin (PE), allophycocyanin (APC), PercP, phycoerythrin-cyanine tandems 7 (PC7), phycoerythrin-cyanine 5 (PC5) and phycoerythrin-texas red (ECD or PETR), preferably the latter two.
- FITC fluorescein isothiocyanate
- PE phycoerythrin
- APC allophycocyanin
- PercP phycoerythrin-cyanine tandems 7
- PC5 phycoerythrin-cyanine 5
- ECD or PETR phycoerythrin-texas red
- the terms “form an effective screen radiation” means that at least 95%, preferably at least 98%, particularly at least 99% and especially 100% of radiation from visible are stopped by the side walls of the bottle due to their structure (nature, treatment or sheathing in particular).
- the term “bottle” refers to preferably a small bottle preferably with a screw, fitted with a cap with or without septum.
- the bottle can be made of polyethylene, polypropylene, polycarbonate, but preferably glass. Its capacity can preferably range from 50 ⁇ l to 50 ml, especially from 100 ⁇ l to 20 ml, especially from 500 ⁇ l to 10 ml and all especially from 1 ml to 10 ml. For example, a 5 ml bottle can be filled per 1 to 2 ml of solution.
- glass vials of about 5 ml.
- the bottom of the bottle also forms an effective radiation shield visible.
- Sheathing techniques are already known in perfumery or coating of vials forming an effective shield against spectrum radiation visible, used for aesthetic purposes.
- Examples include powder coating electrostatic which consists in surrounding the bottles with a septum which is pierced by an electrode which is installed in the bottle to be covered.
- the vials are placed in an enclosure containing a powder sprayed, charged with a sign opposite to that of the bottle.
- the powder is deposited then on the bottle on which it is fixed for example by cooking in an oven at around 180 ° C.
- a epoxy resin powder preferably absorbing in the wavelengths above indicated, particularly 600 to 800 nanometers, black or blue in particular.
- the packaging object of the present invention have very interesting properties.
- the use of covered or treated bottles as described above eliminates the photoinduced oxidation phenomenon and provides excellent stability to fluorochromes-antibody conjugates or Tandem-antibodies.
- the present invention also applies to other conjugates antibody-tandems than those mentioned above, as well as all fluorochromes used in flow cytometry.
- the present application also relates to a method for protecting fluorochromes sensitive to visible light and particularly to lengths wave ranging from 400 to 600 nanometers during their conservation, in which installs said fluorochromes in a bottle with at least the side walls have a structure that forms an effective screen for radiation from the light spectrum between 200 and 800 nm, particularly at wavelengths ranging from 400 to 800 nanometers, more particularly from 400 to 700 nanometers and particularly between 400 and 600 nm.
- Example 1 Coating of a glass bottle with epoxy resin
- Example 3 Manufacture of a glass vial covered with epoxy resin filled with a solution of anti-CD3-Phycoerythrin-cyanine antibody conjugates in PBS, BSA 2 mg / ml, sodium azide 0.1%.
- Vials made according to Example 1 were filled with each 2 ml solution of anti-CD3-Phycoerythrin-cyanine antibody conjugates 5 in phosphate buffer / bovine serum albumin (2 mg / ml) / azide 0.1% sodium.
- flasks commercial and modified products containing anti-CD3 antibodies conjugated to PC5 and ECD fluorochromes underwent a forced degradation test according to the method described in good manufacturing practices (Good Manufacturing Practice (GMP)) of the US Food and Drug Administration.
- GMP Good Manufacturing Practice
- Figure 1 shows the excellent protection of the contents of the vials in implementing the invention.
- the tandems introduced in the bottle BeckmanCoulter Immunotech from the IOTEST range covered with a layer of epoxy varnish according to the electrostatic powdering process have a autofluorescence in FL2 identical to that of the non-irradiated control.
- all the other types of bottles show a light permeability which is translated by a "leak" in FL2, ie an increase in autofluorescence with the appearance of false positive cells.
