    Specifications

  • Product Description
    Guinea Pig anti-Agouti related protein (AGRP) Polyclonal Antibody (Unconjugated), suitable for IHC-Frozen.
  • Application(s) IHC-Frozen
  • Application Details IHC, frozen, PFA fixed material. Not yet tested on paraffin embedded tissue sections. A concentration of 1:1000 to 1:2000 is recommended for IHC with overnight incubations. Permeabilization suggested is 0.1% triton X-100 in blocking buffer. IHC performed in sheep brain (hypothalamus) demonstrates intense staining of cells and terminals. No staining is evident when the primary antibody is pre-absorbed with 0.5 mg/mL of AGRP. In rodents such as rat cell terminal staining is most typically observed without cell body staining. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.
  • Target Agouti related protein (AGRP)
  • Specificity Specificity was demonstrated by immunohistochemistry. This antibody is known to react with human, rat and sheep. Other species have not yet been tested.
  • Target Host Species Mouse
  • Species Reactivity Human, Mouse, Rat, Sheep
  • Antibody Host Guinea Pig
  • Antibody Type Polyclonal
  • Antibody Isotype Mixed
  • Conjugate Unconjugated
  • Immunogen Description A synthetic peptide (SPRRCVRLHESCLGQQVPCCDPCATCYCRFFNAFCYCRKLGTATNLCSRT) corresponding to a region (82-131) within the carboxy domain of mouse agouti related protein. This peptide was conjugated to carrier protein to enhance the immunological response.
  • Purity Description Neat serum
  • Format Lyophilized
  • Reconstitution Instructions Spin vial briefly before opening. Reconstitute in 50 µL sterile-filtered, ultrapure water. Centrifuge to remove any insoluble material.
  • Storage Instructions Store lyophilized antibody at 2-8ºC or lower. After reconstitution, divide into aliquots and store at -20°C, or lower, for optimal long term stability. It is recommended that a reconstituted aliquot is stored at 2-8°C for no longer than 2 weeks. Allocation of an appropriate anti-bacterial agent can increase shelf life by several weeks. Glycerol (1:1) can be added to neat serum for additional stability if intended use does not prevent this.
  • Batch Number Please see item label.
  • Expiration Date

    12 months after date of receipt (lyophilized, unopened vial).

  • Alternative Names Agrp; Agrt; Art; Agouti-related protein;
  • Uniprot Number P56473
  • Uniprot Number/Name P56473 (AGRP_MOUSE)
  • Scientific Background AGRP is the endogenous antagonist of alpha-melanocyte stimulating hormone and has been shown to cause potent stimulation of food intake, and this protein is found in over 90% of Neuropeptide Y containing cells in rats.
  • Shipping Temperature 25°C (ambient)
  • UNSPSC CODE 41116161

    Images, Protocols & SDS

  • The 4% PFA fixed, frozen cryostat section of the sheep hypothalamus was incubated in guinea pig polyclonal antibodies to the mouse AGRP protein at the dilution of 1:1000 overnight followed by incubation with biotinylated secondary antibodies. Cell bodies and nerve terminals in the sheep brain are intensely stained. This figure shows staining of cells when no pre-absorption is performed.

  • Immunohistochemical detection of AGRP in the arcuate nucleus of rat brain using Guinea pig polyclonal antibody to mouse agouti related protein (GP-029-50) incubated at the dilution of 1:1000-2000 in PBS overnight followed by incubation with Alexa-568 goat anti-guinea pig (1:500) secondary antibody. Section is 4% PFA fixed, frozen, cyrosectioned material. In rodents nerve terminals are more often identified than whole cell bodies using GP-029-50
