SREBP-1 Antibody (A-4) is a mouse monoclonal IgG1 kappa light chain antibody that detects SREBP-1 protein of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). anti-SREBP-1 antibody (A-4) is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. SREBP-1 protein plays a crucial role in lipid metabolism, particularly in regulating cholesterol and fatty acid synthesis. SREBP-1 is synthesized as an inactive precursor that resides in the endoplasmic reticulum and nuclear envelope. Upon sterol depletion, SREBP-1 undergoes proteolytic cleavage, releasing a transcriptionally active fragment that translocates to the nucleus to activate genes involved in lipid biosynthesis. This process maintains cellular lipid homeostasis and responds to changes in nutrient availability. Dysregulation of SREBP-1 activity has been implicated in various metabolic disorders, including obesity and type 2 diabetes, highlighting SREBP-1′s importance in metabolic health.

In mouse whole liver lysate, the band was observed near the 50~60 kDa is that normal?

Asked by: pyrk2000
Thank you for your question. We have not yet tested this antibody in mouse whole liver lysate. Our Western blot data in human liver lysate was observed around 125 kDa, the molecular weight of the precursor protein. Because this is a mouse monoclonal primary antibody, and you are using it on samples of mouse tissue lysates, we recommend including a secondary antibody control (omit primary antibody). This will confirm whether or not the band you are seeing may be the result of non-specific binding of the anti-mouse IgG secondary antibody alone (or mouse heavy chain IgG).

Does this antibody identifies both mature and immature forms of SREBP1?

Asked by: Monteiro
Thank you for your question. This mouse monoclonal antibody was raised against amino acids 1119-1147 of SREBP-1 of human origin, but the antibody has not been epitope mapped so further information regarding the epitope location is not available at this time. In Western blot experiments the precursor form is most commonly detected with this antibody.

你好,我想请问为什么SREBP1抗体无法识别亚型SREBP1a和SREBP1c?

Asked by: Maggie吴
Thank you for your question. This mouse monoclonal antibody was specific for an epitope mapping between amino acids 1119-1147 at the C-terminus of SREBP-1 of human origin. Protein accession number P36956. We have not evaluated the reactivity of this antibody with all isoforms. 感谢您的提问。这支抗体的免疫原位于人源的SREBP-1的碳端111--1147个氨基酸序列。蛋白质号码P36956。我们并没有检测和所有亚型的反应性。您可以将抗原序列和您需要检测亚型的序列比对同源性,若同源性大于85%,是能检测该亚型的。

What is the difference between sc-365513 and sc-365513 P?

Asked by: cjMara
Thank you for your question. sc-365513 P is our blocking peptide, meant as a negative control for use with the SREBP-1 antibody, sc-365513.

Hi !! i am interested to use SREBP-1 (Cat #365513) in liver tissue samples. Does this antibody show 2 bands for precursor and nuclear site detection or i should isolate the nuclear fractions to detect it? Thanks !!

Asked by: Candy
Thank you for your question. We have tested this mouse monoclonal, SREBP-1 Antibody (A-4): sc-365513, by Western blot in human fetal liver tissue extracts and did not observe 2 bands for both the precursor and nuclear p68 protein. This was loading 50 µg of protein for detection. Therefore, we would recommend isolating nuclear fractions to detect the nuclear protein.

Rated 5 out of 5 by from 效果很强我之前买了一支CD63的抗体,抗体的性价比好,背景干净,效果强。他们家的抗体总体来说虽然稍微贵一些,但是效果很不错,值得考虑

Rated 1 out of 5 by from pessimo funzionamentoInsodisfatti. L'anticorpo non funziona. Abbiamo provato a cambiare concentrazione, anticorpo secondario, soluzioni di sviluppo ma l'anticorpo non ha mai funzionato su diversi campioni

Rated 2 out of 5 by from I can'tI used the antibody (1:5000 dillution and so on) for rat's cell lysate, but I detected only non-specific bands.

Rated 4 out of 5 by from Buon funzionamento in WBAbbiamo usato questo anticorpo su linee cellulari umane di glioblastoma e funziona bene a una diluizione di 1:100 in BSA.

Rated 2 out of 5 by from deboleHo provato questo anticorpo come campione gratuito in una linea cellulare cardiaca di ratto. La prima diluizione testata (1:500) non ha dato alcun risultato. Un successivo tentativo diluendo l'anticorpo 1:250 evidenzia una banda estremamente debole a 110 kDa corrispondente alla forma non matura della proteina.

Rated 3 out of 5 by from Okay for western blotThis antibody worked pretty good for western blot (rat liver; 25 ug protein; 1:200 dilution; no secondary because the primary is pre-conjugated to HRP). However, the antibody detected a double band at 85 kDa, and the predicted kDa is 125 and 68. So I'm unsure of the reliability, and we won't plan on publishing with this antibody.
