RBITC,o isotiocianato de Rodamina B,es un colorante fluorescente conocido por su grupo isotiocianato que puede unirse covalentemente a aminas primarias en proteínas y biomoléculas[1][2]. RBITC tiene una longitud de onda máxima de excitación de 562 nm y una longitud de onda de emisión de 582 nm[3]. RBITC se utiliza principalmente en biología celular[4],biología molecualr e inmunología para la localización de proteínas[5], el seguimiento celular[6],y el estudio de procesos celulares[7].

Protoclo experimental para el marcaje de proteínas con RBITC:
1.Preparación de la solución RBITX: Disolver RBITC a 10mg/mL en DMSO antes de su uso.Homogeneizar.
2.Preparación de la solución proteica: Disolver la proteína objetivo en fosfato de sodio 0,1M,0,15M tampón NaCI a pH 7,2 para fomar una solución proteica d e1 mg/mL.
3.Reacción de marcado:Transfiere la solución de RBITC a la solución proteica en una proporción molar de 5:1 y remueve suavemente la mazcla en la pscuridad a 4ºC durante 12 horas.
4. Diálisis:Eliminar RBITC no reaccionado mediante diálisis o con una columna de eliminación de tintes.
5.Tras la diálisis,recoger la solución proteica marcada,determinar su concentración y almancenar la prote´´ina marcada con RBITC a 4ºC protegida de la luz hasta que esté lista para su uso.
Este protocolo solo proporciona una guía y debe modificarse según tus necesidades específicas.

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 saline, 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.
