Description

Cy5-SE (Cy5 NHS Ester) triethylamine salt is a reactive dye for the labeling of amino-groups in peptides, proteins, and oligonucleotides. Cy5-SE triethylamine salt is ideal for very cost-efficient labeling of soluble proteins, as well as all kinds of peptides and oligonucleotides Ex=649 nm; Em=670 nm)[1].

In Vitro

Protocol
1.Protein Preparetion
1) In order to obtain the best labeling effect, please prepare the protein (antibody) concentration as 2 mg/mL.
2) The pH value of protein solution shall be 8.5±0.5. If the pH is lower than 8.0, 1 M sodium bicarbonate shall be used for adjustment.
3) If the protein concentration is lower than 2 mg/mL, the labeling efficiency will be greatly reduced. In order to obtain the best labeling efficiency, it is recommended that the final protein concentration range is 2-10 mg/mL.
4) The protein must be in the buffer without primary amine (such as Tris or glycine) and ammonium ion, otherwise the labeling efficiency will be affected.
2.Dye Preparation
Add anhydrous DMSO into the vial of CY5-SE triethylamine salt to make a 10 mM stock solution. Mix well by pipetting or vortex.
3.Calculation of dye dosage
The amount of CY5-SE triethylamine salt required for reaction depends on the amount of protein to be labeled, and the optimal molar ratio of CY5-SE triethylamine salt to protein is about 10.
Example: assuming the required marker protein is 500 μL 2 mg/mL IgG (MW=150,000), use 100 μL DMSO dissolve 1 mg CY5-SE triethylamine salt, the required CY5-SE triethylamine salt volume is 5.73 μL, and the detailed calculation process is as follows:
1) mmol (IgG) = mg/mL (IgG) × mL (IgG)/MW (IgG) =2 mg/mL × 0.5 mL/150,000 mg/mmol= 6.7×10-6 mmol
2) mmol (CY5-SE triethylamine salt) = mmol (IgG) × 10 = 6.7×10-6 mmol×10 = 6.7 × 10-5 mmol
3) μL (CY5-SE triethylamine salt) = mmol (CY5-SE triethylamine salt) ×MW (CY5-SE triethylamine salt)/mg/μL (CY5-SE triethylamine salt) = 6.7 ×10-5 mmol ×855.07 mg/mmol / 0.01 mg/μL = 5.73 μL (CY5-SE triethylamine salt)
4.Run conjugation reaction
1) A good volume of freshly prepared 10 mg/mL CY5-SE triethylamine salt is slowly added to 0.5 mL protein sample
In solution, gently shake to mix, then centrifuge briefly to collect the sample at the bottom of the reaction tube. Don'tmix well to prevent protein samples from denaturation and inactivation.
2) The reaction tubules were placed in a dark place and incubated gently at room temperature for 60 minutes at intervals.For 10-15 minutes, gently reverse the reaction tubules several times to fully mix the two reactants and raise the bar efficiency.
5.Purify the conjugation
The following protocol is an example of dye-protein conjugate purification by using a SepHadex G-25 column.
1) Prepare SepHadex G-25 column according to the manufacture instruction.
2) Load the reaction mixture (From "Run conjugation reaction") to the top of the SepHadex G-25 column.
3) Add PBS (pH 7.2-7.4) as soon as the sample runs just below the top resin surface.
4) Add more PBS (pH 7.2-7.4) to the desired sample to complete the column purification. Combine the fractions that contain the desired dye-protein conjugate.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
