CoraLite directly-conjugated antibodies for IF
Our popular monoclonal and polyclonal antibodies are now available directly conjugated with fluorescent dyes: CoraLite488, CoraLite594 and CoraLite647. They act as perfect tools for immunofluorescence studies requiring multiplex co-labeling studies without the need for secondary antibodies.
CoraLite fluorescent dye-conjugated antibodies are precise and reliable tools for a broad range of fluorescence-based research applications such as immunofluorescence, flow cytometry and ELISA-like assays.
The CoraLite dyes have equivalent brightness to the Alexa Fluor line. Additionally, each fluorophore can be used simultaneously in co-localisation studies due to the minimum overlapping fluorescence spectra. The CoraLite line of fluorescent conjugated antibodies enables faster and simultaneous detection of multiple targets in one experiment.
The only IHC kit to include the primary antibody
The IHCeasy Ready-to-Use IHC Kits are designed to provide all the antibodies and reagents needed to stain your tissue samples, including the primary antibody. Each kit’s protocol has been thoroughly optimised to provide the best staining for your protein of interest. The reagents in the kit require minimal preparation – simply apply them directly to your tissue sample and you’re steps away from obtaining high-quality IHC data.
Proteintech control antibodies
Controls are essential in your research and therefore should not be costly.
Loading control proteins and protein tags provide a reference to evaluate the changes in expression levels of target proteins and help to ensure that any increase or decrease in target protein levels is due to your experimental manipulations, and not due to errors in the Western blot procedure. Proteintech tag and control antibodies include popular controls such as GAPDH, Tubulin and Actin.
Proteintech's highly sensitive ELISA kits using HumanKine immunogens
AuthentiKine™ ELISA kits are Proteintech’s premium line of ELISA kits for measuring minute quantities of human serum factors:
- Ultra-sensitive kits between 10x and 1000xmore sensitive than kits sold by leading competitors.
- The only kits made using actual human proteins from state-of-the-art HumanKine™ human-cell expressed cytokines and growth factors
AuthentiKine ELISA kit development starts with production of HumanKine immunogens. These are human-cell expressed proteins with native glycosylation and processing, in comparison to the industry standard of E. coli derived proteins. Due to having the highest quality immunogens in the industry, the capture and detection antibodies have the highest affinity for human proteins. To best mimic the human sample analyte for optimizing the antibody parameters, HumanKine proteins are used as the standard. This means that the antibody manufacturing and conditions for optimizing are built around using human proteins as they are in nature, resulting in unparalleled sensitivity and accuracy.
About Proteintech
Proteintech actively manufactures and validates primary antibodies in-house to the highest possible standard, thus assuming ultimate responsibility for their quality. As a company founded by researchers, Proteintech now has the largest portfolio of self-manufactured antibodies available, covering two thirds of the human proteome.
With the acquisition of Humanzyme in 2018 and ChromoTek in 2020, the Proteintech catalogue now includes self-manufactured GMP-grade bio-active recombinant proteins and nanobody-based reagents, expanding the direct supply of innovative technology from our bench to the scientist’s bench.
