Background of SMAD3

This antibody is suitable for Cancer, Immunology and Nuclear Signaling research. Smad3 (also known as Mothers against decapentaplegic homolog 3 Mothers against DPP homolog 3, Mad3, hMAD-3, JV15-2 or hSMAD3) is a transcriptional modulator activated by TGF-beta (transforming growth factor) and activin type 1 receptor kinase. These activators exert diverse effects on a wide array of cellular processes. The Smad proteins mediate much of the signaling responses induced by the TGF-b superfamily. Briefly, activated type I receptor phosphorylates receptor-activated Smads (R-Smads) at their c-terminal two extreme serines in the SSXS motif, e.g. Smad2 and Smad3 proteins in the TGF-b pathway, or Smad1, Smad5 or Smad8 in the BMP pathway. Then the phosphorylated R-Smad translocated into nucleus, where they regulate transcription of target genes. Based on microarray and animal model experiments, Smad3 accounts for at least 80% of all TGF-b-mediated response.

Antibody Validation

Boster validates all antibodies on WB, IHC, ICC, Immunofluorescence, and ELISA with known positive control and negative samples to ensure specificity and high affinity, including thorough antibody incubations.

Assay Dilutions Recommendation

The recommendations below provide a starting point for assay optimization. The actual working concentration varies and should be decided by the user.

ELISA: 1:15,000 - 1:30,000
Flow Cytometry: User optimized
IHC: 1:500
WB: 1:2,000 - 1:20,000
This affinity purified antibody has been tested for use in ELISA, immunohistochemistry, and western blot.  Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 48 kDa in size corresponding to phosphorylated Smad3 protein by western blotting in the appropriate stimulated tissue or cell lysate or extract.  Less than 0.2% reactivity is observed against the non-phosphorylated form of the immunizing peptide.  This antibody is phospho specific for dual phosphorylated pS423 and pS425 of Smad3. Stimulation with 2 ng/ml TGF-beta for 1 hour is suggested.

Question

Does P00059 anti-Phospho-SMAD3 S423/S425 antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?

Verified Customer

Verified customer

Asked: 2020-03-30

Answer

You can see on the product datasheet, P00059 anti-Phospho-SMAD3 S423/S425 antibody as been validated on WB. It is best to use PFA for fixation because it has better tissue penetration ability. PFA needs to be prepared fresh before use. Long term stored PFA turns into formalin, as the PFA molecules congregate and become formalin.

Question

I have a question about product P00059, anti-Phospho-SMAD3 S423/S425 antibody. I was wondering if it would be possible to conjugate this antibody with biotin. I would need it to be without BSA or sodium azide. I am planning on using a buffer exchange of sodium azide with PBS only. Would there be problems for me to conjugate the antibody and store it in -20 degrees in small aliquots?

G. Dhar

Verified customer

Asked: 2017-01-16

Answer

We do not recommend storing this antibody with PBS buffer only in -20 degrees. If you want to store it in -20 degrees it is best to add some cryoprotectant like glycerol. If you want carrier free P00059 anti-Phospho-SMAD3 S423/S425 antibody, we can provide it to you in a special formula with trehalose and/or glycerol. These molecules will not interfere with conjugation chemistry and provide a good level of protection for the antibody from degradation. Please be sure to specify this in your purchase order.

Answer

According to the expression profile of erythroleukemia, SMAD3 is highly expressed in erythroleukemia. So, it is likely that anti-Phospho-SMAD3 S423/S425 antibody P00059 will work for WB with erythroleukemia.
