Sample solution is provided at 25 µL, 10mM.
Cy7.5 NHS ester is a NIR dye with low aqueous solubility and long-wave emission. This labeling reagent is amine-reactive derivative of this fluorophore. In vivo, near infrared radiation can be used for imaging applications for it readily penetrates tissues. This product can be used for the labeling of various biomolecules such as proteins and peptides which contain amine groups, to track their distribution in organism in vivo. For biomolecule labeling, the labeling reagent has low aqueous solubility, using of organic co-solvent to dissolve this molecular is necessary for efficient reaction. First, Cyanine dye should be dissolved in organic solvent and then added to a solution of biomolecule in appropriate aqueous buffer.
In mice, Cy7.5 NHS ester labeled insulin (Cy7.5-INS) and were injected via subcutaneous injection at insulin dose of 1 IU/kg. The biodistribution of Cy7.5-Labeled insulin, INS/HTCC, and INS/HTCC-CA11 Nanoparticles was easily analyzed [1].

General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Step 1: Enter information below (Recommended: An additional animal making an allowance for loss during the experiment)
Step 2: Enter the in vivo formulation (This is only the calculator, not formulation. Please contact us first if there is no in vivo formulation at the solubility Section.)
Calculation results:
Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
