Six ranges for the bench: ELISA kits, more than 11,000 antibodies, qPCR and RT-PCR reagents, DNA and RNA extraction kits, molecular biology reagents, and biochemical and cell-based assays.
Each range has its own page with what it covers, how to choose and what to send for a quote.
Quantitative ELISA kits for human, mouse, rat and other species, for hematology, metabolism, neuroscience, oncology and endocrinology research.

More than 11,000 monoclonal, polyclonal, secondary, labelled and control antibodies, validated by western blot, IHC and immunofluorescence.
View the range
Taq DNA polymerase, PCR and qPCR premixes, and reverse transcription kits for cDNA synthesis.
View the range
DNA, RNA and plasmid kits, with sample-specific kits for blood, tissue, plant, fecal and viral RNA samples.
View the range
Cloning systems, DNA molecular weight standards and DNA polymerases for cloning, PCR and gel analysis.
View the range
Enzyme activity and metabolite assay kits, and cell function products for viability, proliferation, apoptosis and cell cycle experiments.

Most orders combine ranges. These are the two chains we quote most often, so the next step is always one link away.
Nucleic acids
Extract
Purify DNA or RNA from blood, tissue, plants, stool or viral samples.
Amplify
Reverse transcribe RNA, then detect or quantify by PCR, qPCR or RT-qPCR.
Clone and size
Clone with high-fidelity polymerases and size products against DNA ladders.
Proteins and cells
Measure function
Read enzyme activity, viability, apoptosis and the cell cycle.
Antibodies
Antibodies are the most widely used detection reagent in biology. This guide walks through each application, what the antibody actually binds in it, and why an antibody that works in one method can fail in another.

ELISA kits
Every ELISA format detects an antigen with an antibody and an enzyme, but they suit different targets. Here is how each works, which one a quantitative kit is likely to use, and how to read the results.

Biochemical and cell assays
Succinate dehydrogenase is the only enzyme in both the Krebs cycle and the electron transport chain, which makes its activity a direct read on mitochondrial function. Here is how the assay works and how to get numbers you can trust.

qPCR / RT-PCR
End-point PCR tells you whether a sequence is there, qPCR tells you how much, and RT-qPCR does the same for RNA. Here is what changes between them and the reagent list for each.

DNA and RNA extraction
Every extraction does the same four things: lyse, separate, wash, elute. The chemistry you use for each step decides yield, purity and how many samples you can run a day.
4 minute read
Biochemical and cell assays
Viability assays measure metabolism, membranes or ATP, never cell number directly. Knowing which one you are measuring explains most odd results and tells you which assay to pick.

Send the whole list at once, across ranges, and we confirm availability, lead time and shipping conditions together.
Special stains, such as Prussian blue for iron and Masson’s trichrome for collagen, protein electrophoresis reagents and other laboratory products are available on request. Send the product name or catalogue number and we check it for you. We also supply laboratory ethanol.

What helps us quote quickly
Most products in these ranges are labelled for research use only. If you need a product for diagnostic or clinical use, tell us the country and intended use and we will confirm its regulatory status there before you order.
Yes. Most requests combine ranges, for example an extraction kit, a reverse transcription kit and a qPCR premix. Send the full list and we quote it together.
A datasheet or kit manual for each product, a certificate of analysis where the manufacturer issues one, and safety data sheets for hazardous components. Tell us if your customs or institution needs anything else.
Products that need it ship cold, at 2–8 °C or on dry ice depending on the product. We confirm the shipping conditions and lead time for your country when we quote.
Catalogue numbers or descriptions, quantities and the delivery country. We’ll confirm availability, lead time and documents.
