High quality monoclonal antibodies for In Vivo research

With over 300 monoclonal antibodies covering a diverse range of research areas, Bio X Cell is your source for purifed antibodies. Bio X Cell products are manufactured in an animal-free facility in tissue culture and purified by affinity chromatography. They are ultra-pure with extremely low endotoxin levels and contain no preservatives or stabilizers. Their reagent portfolio is specialized towards antibodies which are widely used for in vivo and in vitro antigen neutralization and pathway blockade as well as cell specific depletion.

All Bio X Cell products are significantly discounted for customers from academia!

  • Formulated for in vivo application (but can also be used for in vitro)
  • > 95% pure, verified via SDS-PAGE
  • Low endotoxin levels (< 2 EU/mg)
  • Azide and carrier protein free
  • If desired, larger quantities possible (mg to g)
  • High concentrations (3-10 mg/ml)

If additional QC measures are desired, such as murine pathogen testing and binding validation, see Bio X Cell's InVivoPlus™ antibodies.

InVivoMab in our shop


InVivoPlus™ antibodies are structurally and functionally identical to the InVivoMab™ versions, with the added benefit of additional QC measures.

  • Formulated to exceed the rigorous standards required for in vivo work
  • > 95% pure, validated via flow cytometry, ELISA, and/or Western blot
  • Ultra-low endotoxin levels (< 1 EU/mg)
  • Aggregates validated at ≤ 5% via dynamic light scattering
  • Murine pathogen free (screened using ultrasensitive qPCR)
  • If desired, larger quantities possible (mg to g)

Isotype controls

Isotype control antibodies serve as negative controls, allowing researchers to differentiate between non-specific background signals and specific effects of the antibody of interest. They must match the species and isotype of the primary antibody of interest but have no specificity for the target species.

  • > 95% pure via SDS-PAGE
  • Available in InVivoMab™ and InVivoPlus™ formats
  • Ready for in vivo administration
  • Azide and carrier protein free
  • If desired, larger quantities possible (mg to g)
  • High concentrations (3-10 mg/ml)

InVivoPure™ dilution buffers

Bio X Cell's InVivoPure™ dilution buffers are specifically formulated to satisfy the stringent requirements of in vivo applications. They identically match the composition and pH of the buffer Bio X Cell's antibodies are formulated in.

  • Non-toxic, non-antigenic in animal models
  • Ultra-low endotoxin levels (< 0.5 EU/mg)
  • Murine pathogen free

ReadyTag™ antibodies and fusion proteins

These recombinant proteins are produced with a small antigenic sequence to which an antibody can bind specifically. The most commonly used of these tag epitopes include polyhistidine tag, HA tag, c-myc tag, as well as proteins like GFP and GST.

  • Formulated for in vivo applications
  • > 95% purity
  • Low endotoxin levels (< 2 EU/mg)
  • Preservative, stabilizer, and carrier protein free

Fusion proteins

Fusion proteins are constructed by combining the binding domain of a cell surface receptor with the Fc portion of an antibody. The receptor portion functions as a decoy binding site to bind and capture ligand molecules that would otherwise bind to the endogenous receptor.

  • Recombinant antibody (hum/hum)
  • Formulated for in vivo applications
  • > 95% purity
  • Available in InVivoMab™ and InVivoPlus™ formats
  • Preservative, stabilizer, and carrier protein free
