Neutravidin Coated Surface is ideal to bind any biotinylated molecules at wells of Neutravidin Coated Plates, with a minimal non-specific binding.

Neutravidin is a deglycosylated avidin (M.W. 60 kDa) that contains four identical subunits biotin-binding with very high affinity for biotin (Ka= 10-15 M).

It has an isoelectric point near-neutral (pI=6.3) and the lowest non specific binding properties among the known biotin binding proteins.

Compared to the streptavidin, neutravidin in its primary structure does not contain the RYD sequence (Arg-Tyr-Asp): the lack of such a sequence totally eliminates the possibility to interact with the RGD sequence (Arg-Gly-Asp) present in the membrane receptors of a large variety of cells. This makes it very useful in applications where it is important to avoid the non-specific interaction with the cell surfaces.

Neutravidin Coated Surface has similar binding capacity of Streptavidin Coated Surface for biotin and biotinylated molecules and offers a powerful and universal instrument for binding these molecules minimizing non-specific interactions. For example,  Neutravidin Coated Plates are suitable with ELISA assays protocol.

Neutravidin Coated Surfaces main features

Biomat’s Neutravidin Coated plates have the following characteristics:

  • Ready to use
  • Manufactured under ISO:9001 guidelines
  • Post-coated (blocked) for low non specific binding and long term stability
  • All lots are tested for uniformity and reproducibility
  • Certificate of Quality is released for every lot
  • For Research Use Only

Also, Neutravidin Coated Products ensures:

Uniformity

The Neutravidin Coated plates show a CV% less than 5 using biotin-HRP as detector and TMB as substrate.

Storage and Stability

The Neutravidin Coated products, if unopened, are stable at 2-8°C until the expiration date printed on the label. If opened, store in closed pouch with desiccant and use within the expiration date.

Coating

Neutravidin is coated using 100 µl/well.

Binding capacity for small molecules (e.g. d-biotin)

The Neutravidin coated wells were incubated with biotin solutions, in an ELISA format, using biotinylated peroxidase as detector and TMB as substrate.

Result:

~ 5 pMol d-biotin/well

Binding capacity for big molecules (e.g. HIgG)

The Neutravidin coated wells were incubated with biotinylated HIgG in an ELISA format using HIgG-HRP as a detector and TMB as substrate.

see Binding Capacity technical note

Result:

~ 100 ng/ml biotinylated IgG
