Industry-Leading Proteins

Over 40 years of protein manufacturing knowledge and experience enables us to be first to market in new areas, as with our range of avi-tagged proteins and new proteins for COVID-19 research.

Unbeatable Biological Activity

Our scientists go the extra mile to develop proteins of the highest quality for your business.

  1. Methods to guarantee accurate protein folding ensure that our proteins are biologically relevant
  2. Over 2000 different bioactivity assays performed on our catalog proteins, we provide the most accurate and relevant activity data for your protein of interest

High Lot-to-lot Consistency and bioactivity of Human R-Spondin 1. Three independent lots of Recombinant Human R-Spondin 1 (R&D Systems, Catalog # 4645-RS) were tested for their ability to stimulate activation of beta-Catenin using a TOPflash beta-Catenin/TCF reporter assay in the HEK293T human kidney cell line, in the presence of 5 ng/mL Recombinant Mouse Wnt-3a (R&D Systems, Catalog # 1324-WN). Each trace represents data obtained from Recombinant Human R-Spondin 1 from a different manufacturing run.

Quality and Consistency Time After Time

We know that our partners need dependable products that deliver reproducible results, time after time. By investing in a Bio-Techne protein, you benefit from our rigorous quality control processes.

Extensive Quality Control

Our QC measures include lot specific Certificates of Analysis, dedicated manufacturing space, monitoring of product stability over shelf life and transparent traceability of raw materials.

Lot-to-Lot Consistency

Each new product lot is tested side-by-side with previous lots for purity, biological activity, and endotoxin level. We also routinely test a sample from an earlier lot to control for variability in the assay itself.

Low Endotoxin And Microbial Bioburden

Each new production lot is assessed for endotoxin using the LAL assay to ensure levels as low as <0.01 EU/ug. Microbial contamination is ruled out using both direct plating and broth dilution.

Accurate Proteins Sequences

N-terminal amino acid sequence analysis is performed for every recombinant protein we develop.

Buffer Systems

We take great care that our proteins are made, stored and shipped in physiologically relevant buffers for optimal bioactivity.
