NOTE: Antibodies or other proteins submitted for conjugation should be free of carrier proteins such as BSA or gelatin - purification of proteins is available for an additional charge.  Amine containing buffers need not be removed - a buffer exchange is included as part of the service.
Standard labeling of antibodies or other proteins (that are free of carrier proteins) with fluorescein (FAM, fluorescein-EX, DTAF or FITC), tetramethylrhodamine (TAMRA or TRITC), Texas Red® sulfonyl chloride, or similar dyes and with biotin-XX:
1-5 mg of protein $1,175
6-10 mg of protein $1,365
>10 mg of protein Inquire

Standard labeling of antibodies or other proteins (that are free of carrier proteins) with Alexa Fluor® dyes, Cascade Blue®, Marina Blue®, Pacific Blue™, Pacific Orange™, QSY® dyes or other Invitrogen proprietary fluorescent organic dyes (for internal research and development use only):
1-2 mg of protein $1,465
3-5 mg of protein $1,700
>5 mg of protein Inquire

Conjugations of phycobiliproteins (R-PE, B-PE or XL-APC) to antibodies or other proteins (for internal research and development use only):
1-2 mg of protein $1,565
3-5 mg of protein $1,955
>5 mg of protein Inquire

Conjugations of proteins (e.g. HRP or alkaline phosphatase) to antibodies or other proteins (for internal research and development use only):
1-2 mg of protein $1,595
3-5 mg of protein $1,955
>5 mg of protein Inquire*

Conjugates of proteins of molecular weight <60,000 to phycobiliproteins may cost more.

*Conjugates prepared from dyes that are patented by Invitrogen or that have patents pending are for internal research and development purposes only and are not for resale or for use in commercial testing services, except under license from Invitrogen. Certification that the conjugates are not for resale or other commercial use is required before we perform conjugations of >=5 mg of your protein with our Alexa Fluor®, Oregon Green®, Rhodamine Red®-X, Texas Red®-X, BODIPY®, Cascade Blue®, Marina Blue®, Pacific Blue™ Pacific Orange™, QSY® 7, QSY® 9 and QSY® 21 dyes. Please inquire for licensing terms at probesbusdev@invitrogen.com. Conjugates of phycobiliproteins are covered by patents owned by Stanford University and can be sold for commercial use only by their licensees.

Special Services

Inquire for the cost of conjugations to other dyes, enzymes or other biomolecules; purification of a protein, analysis by microscopy and flow cytometry; labeling of other functional groups, special purification or handling and bioassays may also be available.
