R-Phycoerythrin (PE) is isolated from red algae. Its primary absorption peak is at 565 nm with secondary peaks at 496 and 545 nm. Our RPE-iFluor® 660 Tandem is an excellent color for multicolor analysis of multiple targets with flow cytometry. It has a unique emission located between the emission Cy5 and that of Cy5.5, providing a new color for spectral flow cytometry. ReadiUse™ Preactivated PE-iFluor® 660 Tandem is an activated PE protein, and can be easily conjugated to antibodies with much higher conjugation yield than the conventional PE.
Components
Example protocol
AT A GLANCE
Important PE-iFluor™ 660 Tandem was premodified with our Buccutite™ FOL. Your antibody (or other proteins) is modified with our Buccutite™ MTA to give MTA-modified protein. The MTA-modified protein readily reacts with FOL-modified PE-iFluor™ 660 Tandem (provided) to give the desired PE-iFluor™ 660 Tandem-antibody conjugate.
SAMPLE EXPERIMENTAL PROTOCOL
Preparation of pre-activated Antibody with Buccutite™ MTA
- Reconstitute Buccutite™ MTA in DMSO at ~10 mg/mL.
Note Store unused MTA at -20 °C; it can be used for up to two freeze and thaw cycles. - Prepare target antibody (Ab) in pH = 8.5 - 9.0 buffer at a concentration above 1 mg/ml.
- Add the MTA to Ab solution at the ratio of 8 - 10 µg MTA/100 µg Ab.
- Mix well and react at room temperature for 60 minutes, rotating during the reaction.
- Purify the reaction mixture with a desalting column to remove any unreacted MTA. Exchange the buffer to PBS or another buffer of your choice.
- Collect the MTA-activated Ab. Estimate the concentration by 70% yield of the original starting amount.
Conjugate with Pre-activated PE-iFluor™ 660 Tandem
- Reconstitute pre-activated PE-iFluor™ 660 Tandem in 100 µL ddH2O to 10 mg/mL.
Note Reconstituted pre-activated PE-iFluor™ 660 Tandem is not stable and can not be stored for more than one month. - Add pre-activated PE-iFluor™ 660 Tandem directly to MTA-activated target Ab solution at the ratio of 300 µg PE-iFluor™ 660 Tandem/100 µg MTA-activated Ab.
- Rotate the mixture for 1 - 2 hours at room temperature.
- The Ab/PE--iFluor™ 660 Tandem conjugates are now ready to use.
Note The antibody conjugate should be stored at >0.5 mg/mL in the presence of a carrier protein (e.g., 0.1% bovine serum albumin) and 0.02-0.05% sodium azide.
Note The Ab/PE-iFluor™ 660 Tandem can be stored at 4 °C for two months. - Optional: Ab/PE-iFluor™ 660 Tandem can be further purified through size exclusion chromatography to get better performance.
