SEE ALSO...

PECAM-1 Antibody (H-3) is a mouse monoclonal IgG1 kappa light chain antibody that detects PECAM-1 protein of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry with paraffin-embedded sections (IHCP), and enzyme-linked immunosorbent assay (ELISA). PECAM-1 Antibody (H-3) 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. PECAM-1, also known as CD31, is a crucial glycoprotein that plays a significant role in mediating cell-cell adhesion, particularly in the vascular system, where PECAM-1 is predominantly expressed on the surfaces of endothelial cells, platelets, and certain leukocytes. PECAM-1 is essential for maintaining the integrity of blood vessels and facilitating leukocyte transmigration during inflammatory responses. PECAM-1 function is vital for normal angiogenesis and tissue repair, and dysregulation of PECAM-1 has been implicated in various pathological conditions, including cancer metastasis and cardiovascular diseases. PECAM-1′s ability to interact with other adhesion molecules, such as integrins, further underscores PECAM-1′s importance in cellular signaling and immune responses. Anti-PECAM-1 antibody (H-3) enables researchers to gain valuable insights into the mechanisms of cell adhesion and the role of PECAM-1 in health and disease.

Hola, para este anticuerpo es mejor para bloqueo leche, BSA %??, y que porcentaje de tween? y para lavar, PBS o TBS? Hello, for this antibody is better for blocking milk, BSA, %?? and what percentage of tween? and to wash, PBS or TBS?

Asked by: MARIACONSUELO
Thank you for your question. We recommend blocking with 5% milk or 3% BSA with 0.05% Tween-20 for Western blot. We wash with TBS but PBS would work to. If you have additional questions, please contact Technical Support at 1800-457-3801 option 2, by emailing scbt@scbt.com or by live chat on our website at www.scbt.com so we may further assist you.

Is PECAM1 antibody (H3) conjugated to Alexa Fluor 594 stable to fixation and the subsequent solvents such as ethanol and xylene? If kept dark will it still fluoresce?

Asked by: Barb
Thank you for your question. Yes, the Alexa Fluor 594 conjugated antibody is a bright, red-fluorescent dye that provides stable imaging for immunofluorescent staining applications. Alexa Fluor 594 dye is pH-insensitive over a wide molar range. We recommend to perform all steps in the dark. Please see our recommended protocol below for details. https://www.scbt.com/scbt/resources/protocols/immunofluorescence-cell-staining

Rated 5 out of 5 by from Ottimo funzionamento!Ho provato questo ab in WB su lisati da tessuto murino e funziona molto bene!
Date published: 2025-06-04
Rated 4 out of 5 by from It works in IFI tried this antibody in frozen section of mouse mesenteric arteries and it worked at 1:50 dilution
Date published: 2023-03-08
Rated 4 out of 5 by from Works wellI used the dilution with 1:100 for IF in mouse brain, without any antigen retrieval processes. When I tried the antigen retrieval with Hcl/ heating, it stained but not as good as the tissue stained normally. If you are doing the IF, then I recommend not to use the antigen retrieval.
