Smad4 Antibody (B-8) is a mouse monoclonal IgG1 kappa light chain antibody that detects Smad4 of mouse, rat, and human origin through various applications including western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry (IHC), flow cytometry (FCM), and enzyme-linked immunosorbent assay (ELISA). Smad4 monoclonal antibody (B-8) is offered in both non-conjugated and multiple conjugated forms, such as agarose, horseradish peroxidase, phycoerythrin, fluorescein isothiocyanate, and various Alexa Fluor® conjugates. Smad4, also known as DPC4, plays a crucial role as a central mediator in the transforming growth factor-beta (TGFβ) and bone morphogenetic protein (BMP) signaling pathways, which are essential for regulating cellular processes such as proliferation, differentiation, and apoptosis. By interacting with other Smad family members, Smad4 facilitates transcriptional regulation of target genes, thereby influencing developmental processes and tissue homeostasis. Smad4 (B-8) antibody specificity allows researchers to effectively study function and interactions, particularly in the context of TGFβ/BMP signaling, where Smad4 is essential for mediating pathway effects. Additionally, Smad6 and Smad7 act as negative regulators of TGFβ signaling, highlighting Smad4 importance in maintaining the balance of these critical cellular processes.

Can this antibody act as IF in rats

Asked by: renxue
Thank you for your question. Anti-Smad4 Antibody (B-8) is recommended for detection of Smad4 of mouse, rat and human origin by WB, IP, IF, IHC(P), FCM and ELISA and would thus be suitable for your proposed experiment.

Rated 1 out of 5 by from no signalI have tried different dilutions of Smad4 antibody(B8) from 100 to 1000, none of them worked. Protein loading is 40ug of nuclear fraction or cytosolic fraction from induced human alveolar type 2 cells.

Rated 2 out of 5 by from Very faint bands in Western blottingMay need lots of protein amounts; disappointing that the bands were hardly visible.

Rated 5 out of 5 by from Reliable antibobyI used this SMAD4 ab for IHC and the signal is nice.
Date published: 2023-07-19
Rated 5 out of 5 by from Good one for immunoprecipitationWe used the Ab for immunoprecipitation of endogenous as well as transfected SMAD4 from HEK293T cells. It worked very well - 1 µg Ab (5µl) was incubated with 250µl of lysate obtained from a 70-80% confluent 10cm dish. A specific (absent in IgG control) distinct right-sized band with good enrichment was obtained in all IP samples. It was used for studying interactions as well as SMAD4 ubiquitination.

Rated 3 out of 5 by from Buon funzionamento!Ho provato questo articolo su un gel stain free con 60 ug di lisato proteico. L'anticorpo è stato utilizzato nella concentrazione di 1:500 e il secondario 1:5000. La banda è risultata definita e senza aspecifico.

Rated 5 out of 5 by from my review for Smad4 (B-8, sc-7966) antibodyI tested a free antibody for Smad4 (sc-7966) antibody using mouse fibrotic kidney samples for Western blot. We loaded 80 ug proteins in each slot in the SDS gel. The antibody was diluted in 1:500 in 3% BSA/PBST and incubated overnight with the blot. We can observe a very clear band around 55 kd. We have repeated this experiment several times and used the fresh diluted antibody on the fresh blot.
