DTAF has absorption and emission properties nearly identical to fluorescein isothiocyanate (FITC) and DTAF- and FITC-labeled antibodies are similar in terms of preparation and specificity of immunofluorescence.
However, DTAF is superior to FITC with regard to cost, purity and stability.
Also, DTAF-labeled rabbit IgG conjugates can be quickly and efficiently fractionated by simple ammonium sulfate precipitation to yield preparations free of both over- and under-conjugated material.
In addition, over-conjugated protein can be readily removed from DTAF:IgG conjugates by appropriate adjustment of pH and temperature.
Applications:Suitable for use in FLISA, Immunofluorescence and Fluorescent Western Blot.
Other applications not tested.
Recommended Dilutions:FLISA: 1:10,000-1:50,000Immunofluorescence: 1:1000-1:5000Optimal dilutions to be determined by the researcher.
Label (FITC):Absorption Wavelength: 495nmEmission Wavelength: 528nmFluorochrome/Protein Ratio: 3 moles FITC per mole of IgG
Storage and Stability:Store product at 4°C if to be used immediately within two weeks.
For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C.
Aliquots are stable at -20°C for 12 months after receipt.
Dilute required amount only prior to immediate use.
Further dilutions can be made in assay buffer.
Caution: FITC conjugates are sensitive to light.
For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
