HumanKine® recombinant proteins are created in HEK293 cells using animal free components

Proteins co-expressed in bacteria will not possess post- translational modifications, e.g., phosphorylation or glycosylation. For activity, many proteins require glycosylation and processing available exclusively in eukaryotic systems; specifically human systems for authentic human proteins.

All Humankine® recombinant proteins are produced in Proteintech's in-house cGMP grade laboratory adhering to strict quality control regulations.

  • Authentic human proteins

  • Native human conformation & post-translational modifications

  • High bioactivity & stability

  • Seamless transition from research to cGMP


Nano-Traps are ideal for fast, reliable and efficient one-step immunoprecipitation and co-immunoprecipitation. Nano-Traps comprise of Nanobodies conjugated to beads.

Nano-Secondary reagents

Nano-Secondary® reagents use a novel class of secondary antibodies for higher resolution & cleaner images. These reagents consist of Nanobodies conjugated to fluorescent dyes binding to conventional antibodies.


Chromobodies® are fluorescent nanoprobes for real-time and live-cell imaging of intracellular endogenous proteins. Chromobodies are Nanobodies that are genetically fused to a fluorescent protein such as GFP.

Nano-Booster &

ChromoTek's Nano-Boosters & Nano-Labels are very small fluorescent probes optimzed for confocal and super-resolution microscopy. They consist of Nanobodies conjugated to fluorescent dyes.


Nano-Caps® are optimized for effective and cost-efficient protein purification. Nano-Caps consist of Nanobodies conjugated to agarose.


Nano-CaptureLigands are optimized to specifically immobilize human, mouse, and rabbit antibodies to streptavidin/avidin. Nano-CaptureLigands are biotinylated Nanobodies.


Suitable for conjugation to dyes, biotin, beads, surfaces etc. via NHS ester reaction.
