应用 Ab评论 说明
WB 1/5000. Detects a band of approximately 25 kDa (predicted molecular weight: 25 kDa).

Unpurified format: 1/1000000

IHC-P 1/50 - 1/250. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.

Enzymatic antigen retrieval (using protease) also has been found to work and may acheive better results


  • 功能Can interact with DNA and histones and may scavenge nuclear material released from damaged circulating cells. May also function as a calcium-dependent lectin.
  • 组织特异性Found in serum and urine.
  • 疾病相关Note=SAP is a precursor of amyloid component P which is found in basement membrane and associated with amyloid deposits.
  • 序列相似性Belongs to the pentaxin family.
    Contains 1 pentaxin domain.
  • 翻译后修饰N-glycosylated with a complex biantennary oligosaccharide chain with a sialic acid at the end (disialo-SAP). Monosialo-SAP as well as asioalo-SAP are also detected (PubMed:15174148).

    Diluting and blocking buffer: 5% NFDM /TBST 

  • ab45151 staining Serum Amyloid P in human endometrial carcinoma tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and antigen retrieval was by heat mediation in a EDTA buffer. Samples were incubated with primary antibody at a dilution of 1/50. A goat anti-rabbit IgG H&L (HRP) ab97051 was used as the secondary antibody at 1/500.

    Negative control 1: PBS in place of primary antibody.

Thank you for waiting.

I have contacted my lab colleagues who confirmed product ab45151 from lot number 1351175 has a concentration of 0.426 mg/ml.

I hope this helps and if we can assist further, please do not hesitate to contact us.

Thank you for contacting Abcam.

Please find attached the IHC-P protocol that we discussed on the telephone. Also let me know if the protocol variations that we discussed are not successful.

Hope you have a great weekend.
