Cy5.5 maleimide is a thiol reactive dye which is capable of selective labeling of proteins which contain sulfhydryl groups. Cy5.5 maleimide has near infrared emission that makes it suitable for bioimaging applications. This reagent can replace Alexa Fluor 680 and DyLight 680. 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.
Cy5.5-NLP conjugate was synthesized by the NLP peptide and the Cy5.5-maleimide in 100 μL of anhydrous DMF, to which 10 μL of DIPEA was added. In the Her2/neu positive (SKBR-3 and BT474) or Her2/neunegative (MDA-MB-231) breast cancer cells, intracellular localization of Cy5.5-labeled peptide conjugates make the effects visible [1].

| 溶解度 | ≥ 74.1mg/mL in DMSO | Storage | 24 months after receival at -20°C in the dark. Transportation: at room temperature for up to 3 weeks. Avoid prolonged exposure to light. Desiccate. |
| 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. |

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.
