EasyLink Cy7 Conjugation Kit provides a simple and quick process to conjugate your primary antibodies with Cy7. Cy7 is a far red fluorescent dye which has an excitation wavelength of 753nm and an emission wavelength of 775nm.
The conjugated antibody can be used straight away in WB, ELISA, IHC etc
Learn more about buffer compatibility, protein/secondary antibody conjugation and labelling chemistry in our FAQs.
This kit is sufficient for 1 labeling reaction of 1-2mg of antibody.
The purified antibody to be labeled should ideally be in 10-50mM amine-free buffer (e.g. MES, MOPS, HEPES, PBS), pH range 6.5 to 8.5. If the buffer is more concentrated or outside this pH range contact the technical support team.
Common non-buffering salts (e.g. sodium chloride), chelating agents (e.g. EDTA), and sugars have no effect on conjugation efficiency. Azide (0.02 to 0.1%) and BSA (0.1 to 0.5%) have little or no effect. Glycerol up to 50% has no effect.
Avoid buffer components that are nucleophilic, as these may react with EasyLink chemicals. Primary amines (e.g. amino acids or ethanolamine) and thiols (e.g. mercaptoethanol or DTT) fall within this class (Note: Tris-based buffers should be avoided). If your buffer contains primary amines and/or thiols, you should consider using our Concentration and Purification Kits (ab102778 or ab102784).
Recommended amount and volume of antibody for optimal results
|Pack size||Amount of antibody||Volume of antibody|
|Up to 20 µg||10-20 µg||4-10 µl|
|Up to 200 µg||100-200 µg||40-100 µl|
|Up to 2 mg||1-2 mg||400-1000 µl|
Antibody concentrations of 1-4 mg/ml generally give optimal results. For conditions outside the suggested ranges contact the technical support team.
Storage of conjugates
Storage at 4°C is recommended for any conjugate. A preservative may be desirable for long-term storage. Other storage conditions may also be satisfactory. The best conditions for any particular conjugate must be determined by experimentation.
Labeling of the antibody will not work if the conjugation blocks the active paratope. This situation is rare.
