供应Cy7.5 NHS ester
供应Cy7.5 NHS ester，该产品由西安瑞禧生物科技有限公司供应。
Cy7.5 is near infrared dye with very long-wave emission. This product is amine-reactive derivative of this fluorophore.
Near infrared radiation readily penetrates tissues and can be used for imaging applications in vivo.
This product can be used for the labeling of various biomolecules containing amine groups, such as proteins and peptides, to track their distribution in organism in vivo.
Increased rigidity of central polymethyne moiety allows to increase quantum yield by 20% compared to parent structure.
