    小鼠单克隆抗体[4H9] to Corticotropin Releasing Factor
  • 特异性Reacts with CRF. Does not react with bovine serum albumin, insulin, ovalbumin or epidermal growth factor.
  • 经测试应用适用于: ELISA, IHC-P, IHC-Fr, Inhibition Assaymore details
  • 种属反应性
    与反应: Human
    预测可用于: Rat
  • 免疫原

    Full length protein (Human)

  • 表位The unique lysine residue (Lys-36) is likely to be involved in the antigenic determinant of ab35748. Lysine modification by CA blocks binding completely.



Our Abpromise guarantee covers the use of ab35748 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
ELISA Use at an assay dependent concentration.
IHC-P Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval via the microwave method before commencing with IHC staining protocol.
IHC-Fr 1/100 - 1/7000.
Inhibition Assay Use at an assay dependent concentration. Human serum, containing CRF-binding protein, inhibits the binding of CRF to this antibody.


  • 相关性CRF precursor is a 41-amino acid peptide derived from a 196-amino acid preprohormone. CRF is a neuroendocrine hormone secreted by the paraventricular nucleus (PVN) of the hypothalamus and is a key player in the hypothalamic pituitary adrenal axis. It is also synthesized in peripheral tissues, such as T lymphocytes and is highly expressed in the placenta. Neuronal CRF is important in a variety of diverse roles including, memory, depression, stress, kidney function, parturition, metabolism and feeding (to mention a few).

  • ab35748 staining Corticotrophin Releasing Factor in Rat brain tissue by Immunohistochemistry (Frozen sections). The sections were fixed in methanol prior to blocking with PBS with 1.5% goat serum for 20 minutes at 22°C. The primary antibody was diluted 1/100 in the blocking buffer and incubated with the sample for 10 hours at 4°C. A Dylight® 594-conjugated polyclonal antibody was used as the secondary antibody, diluted 1/80.

Thank you for contacting us.

As we discussed on the phone, adding a BSA block and trying a shorter antigen retrieval time may help to reduce the background for ab7963, ab59023, and ab75168, while trying a 1:100 dilution for ab35748 may help t...

Thank you for contacting us and your patience while I double checked with the laboratory.

The antibody will recognize an epitope around the Lysine 36 of the mature protein, as the lysine modification blocks the binding completely. The lysine ...
