Proteins

Aquin offers an extensive selection of purified recombinant and natural:

• Cytokines
  
• Chemokines
  
• Proteases
  
• Growth factors
  
• Adhesion molecules
  
• Neurotrophic factors
  
• Developmental proteins
  

Human, mouse, and rat proteins are our focus. In addition, we have proteins from the following:

• Bovine, Porcine
  
• Chicken, Xenopus, Rhesus macaque, Zebrafish
  
• Drosophila and other insects
  
• Viral and bacterial proteins
  

Our proteins feature:

Quality Control

• Each new lot is tested side-by-side with a previous lot for biological potency, endotoxin level, and purity.
  
• Minimal lot-to-lot variability
  

Biological Activity

• Easured with an appropriate biological system
  
• Tested to ensure biological activity is consistent with literature-based expectations

Purity

• Recombinant proteins are typically over 95% pure.
  
• Ensures that the experimental outcome is a result of the protein of interest and not due to the presence of a contaminant

Endotoxin Level

• Each new production lot of protein is assessed for endotoxin using the Limulus Amoebocyte Lysates (LAL) assay.
  
• Low endotoxin levels are essential when proteins are used in biological systems that are sensitive to its effect.

Formulation

Most recombinant proteins are lyophilized from a sterile filtered solution containing a carrier protein, usually bovine serum albumin (BSA) at 50 micrograms per 1 microgram of the protein of interest.

• Each new production lot of protein is assessed for endotoxin using the Limulus Amoebocyte Lysates (LAL) assay.
  
• Low endotoxin levels are essential when proteins are used in biological systems that are sensitive to its effect.
  
  
  • Gives the lyophilized protein greater stability
  • Allows easy handling and storage
    
  • Maximizes recovery upon reconstitution
    
    
• For applications where carrier protein is undesirable (e.g. in vivo experiments), carrier-free proteins are available
  
• Our recombinant enzymes are in solution and ready to use.

Bulk Quantities

• When experimental protocols require large quantities of a particular protein, special bulk pack sizes can be purchased. This will reduce the cost per unit mass. Please contact us for a bulk order quote.

Animal-Free™ Recombinant Proteins

To support developing research and bioproduction demands, we offer products manufactured in a laboratory exclusively dedicated to the production and purification of recombinant proteins using all non-animal reagents. Every stage of our established fermentation and protein purification methodologies has been specifically modified for the manufacture of animal-free products. Animal-free proteins are important for researchers concerned with experimental variables caused by trace animal components or mammalian pathogens and are particularly important for ex vivo cell therapy studies. Products that are generated under animal-free conditions share the same biological activity as those produced in a typical laboratory environment.

Antibodies

Aquin offers a wide range of antibodies to cytokines, adhesion molecules, proteases, neurotrophic factors, stem cell factors, signal transduction molecules and developmental proteins. Monoclonal and polyclonal antibodies are available, labeled or unlabeled. The majority of polyclonal antibodies are supplied as antigen affinity-purified IgG preparations.

• human
  
• mouse
• rat
  

Additional Antibody Products

• Antibody Controls
  
• Secondary Antibodies

Quality Control

Each antibody is manufactured under controlled conditions, undergoing rigorous quality control testing to ensure lot-to-lot consistency and outstanding performance in a variety of applications

Endotoxin Level

Neutralizing antibodies are tested to ensure low endotoxin levels which is reported on individual datasheets. The formulation of most antibodies does not contain azide or other preservative.

Specificity

All antibodies are tested for cross-reactivity with related molecules by direct ELISA to ensure specificity.

Bulk Quantities

When experimental protocols require large quantities of a particular antibody, special bulk pack sizes can be purchased. This will reduce the cost per unit mass. Please contact us for a bulk order quote.

Aquin Antibody Types

Polyclonal

Polyclonal antibodies offer multiple epitope recognition. Anti-sera and whole immunoglobulin (Ig) preparations contain a large amount of non-specific Ig, which could lead to non-specific antibody binding. Antigen column affinity chromatography eliminates non-specific IgG making these specific IgG preparations, in general, 10-fold more potent.

Monoclonal

Monoclonal antibodies offer monospecificity, recognizing a single epitope. All new R&D Systems' monoclonal antibodies are derived from hybridoma culture supernatants rather than ascites fluid, and are purified using either protein A or protein G columns.

Secondary Antibodies

Secondary antibodies are offered against goat, hamster, human, mouse, rabbit, rat, and sheep IgG, in addition to chicken IgY and are conjugated to a range of fluorochromes, biotin, or horseradish peroxidase to suit the needs of particular applications.
