Scientific Overview

Normal Goat Serum (10%) is a pre-diluted blocking reagent derived from healthy, non-immunized goats. It contains a broad spectrum of proteins that effectively saturate non-specific binding sites on tissues, membranes, and assay surfaces. This ready-to-use 10% formulation is ideal for minimizing background staining and improving signal specificity in antibody-based assays, including those using goat-derived secondary antibodies.

Key applications include:

  • Blocking in immunohistochemistry (IHC) and immunofluorescence (IF)
  • Antibody diluent for primary and secondary antibodies
  • Reduction of non-specific binding in Western blotting and ELISA
  • General serum control in immunological protocols

Usage & Handling Guidance

Store at -20C. Thaw at 28C or room temperature before use. Typical final concentration for blocking: 510% (already provided at 10%). For antibody dilution, use 15% in PBS-T. Heat-inactivate (56C for 30 min) if complement activity is a concern.

  • Blocking step: Incubate with 10% normal goat serum for 3060 min
  • Diluent: Dilute antibodies in 15% normal goat serum
  • Aliquoting: Recommended to avoid repeated freezethaw cycles

Frequently Asked Questions (FAQ)

  • What is the advantage of the 10% pre-diluted format?
    It is ready-to-use for blocking and dilution, reducing preparation steps and variability.
  • Should I heat-inactivate the serum?
    Yes, if complement-mediated interference is a concern in your assay (56C for 30 min).
  • What concentration should I use for blocking?
    The 10% solution can be used directly or further diluted to 5% depending on the protocol.
  • How should I store it?
    Store at -20C. Thaw gently and aliquot to avoid repeated freezethaw cycles.
  • Is it suitable when using goat secondary antibodies?
    Yes. Normal goat serum is commonly used as a blocker even when goat secondaries are employed.
