Description

Mouse Monoclonal Antibody

Description: The monoclonal antibody P1H12 recognizes CD146 also known as MUC18, s-endo, Endo-CAM and Mel-CAM, which is a member of the Ig superfamily of proteins. The expression of CD146 is found on endothelial cells, bone marrow fibroblasts and some tumors (especially melanoma). Recently mesenchymal stromal cells and endometrial stromal cells have also been shown to express CD146. The presence of CD146 on circulating blood cells have been confined to a subset of T cells rather than circulating endothelial cells, as expression of other endothelial markers (CD31 and CD51/61) is negative. Expression can be found on activated lymphocytes. The protein is heavily glycosylated with more than 50% of the mass from carbohydrates. The antibody P1H12 has been reported to crossreact to mouse, rabbit, canine, but not rat. Applications Reported: This P1H12 antibody has been reported for use in flow cytometric analysis. Applications Tested: This P1H12 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 μL (0.125 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. eFluor® 450 is an alternative to Pacific Blue®. eFluor® 450 emits at 445 nm and is excited with the Violet laser (405 nm). Please make sure that your instrument is capa...

CD146, also known as MCAM (Melanoma Cell Adhesion Molecule), is an integral membrane glycoprotein belonging to the immunoglobulin superfamily. It is heavily glycosylated, with more than 50% of its mass derived from carbohydrates. CD146 is primarily expressed on endothelial cells at cell-cell junctions, playing a crucial role in cell adhesion and the cohesion of the endothelial monolayer in vascular tissue. In addition to endothelial cells, CD146 is expressed on bone marrow fibroblasts, mesenchymal stromal cells, endometrial stromal cells, and some tumors, particularly melanoma. It has also been observed on a subset of circulating T cells and activated lymphocytes, but not on circulating endothelial cells, as indicated by the absence of other endothelial markers such as CD31 and CD51/61. CD146 functions as a calcium-independent cell adhesion molecule and may also act as a signal transduction molecule. It is involved in the recruitment of Fyn kinase and the subsequent tyrosine phosphorylation of intracellular proteins, which are important for actin cytoskeleton assembly. This signaling role includes triggering tyrosine phosphorylation of FYN and PTK2 and causing a transient increase in intracellular calcium concentration. In the context of cancer, CD146 expression may facilitate the interaction of melanoma cells with the vascular system, enhancing hematogenous tumor spread. Additionally, CD146 could serve as an adhesion molecule active in neural crest cells during embryonic development, highlighting its diverse roles in both normal physiological processes and disease states.

Frequently Asked Questions (FAQs)

I am unable to analyze my cells stained with eFluor Organic Dyes today. What options do I have?

Our options will depend on the samples you are analyzing.

If cell viability is not critical, you can store your stained samples at 4 degrees C or on ice overnight in the dark and analyze the following day.

For samples stained with eFluor organic fluorochromes, we recommend that cells be suspended in 100 uL of Flow Cytometry Staining Buffer (Cat. No. 00-4222) and 100 uL of eBioscience IC Fixation Buffer (Cat. No. 00-8222); samples can be incubated for up to 3 days at 4 degrees C in the dark. Alternatively, the 1-step Fix/Lyse Solution (Cat. No. 00-5333) can be used. This is a great option when working with whole blood but also works for other cell types.

Can the eFluor Organic fluorochromes be used for intracellular staining?

Yes, the eFluor Organic fluorochromes can be used for intracellular staining. The eFluor organic fluorochromes maintain bright signal and require minimal changes in compensation when fixed with eBioscience IC Fixation Buffer (Cat. No. 00-8222-49) and Permeabilization Buffer (Cat. No. 00-8333-56) or 1-step Fix/Lyse Solution (Cat. No. 00-5333-54, 00-5333-57) (as compared to live cells).

What is the difference between eFluor Organic Dyes and eVolve Qdots?

The eFluor Organic Dyes (eFluor 450, APC-eFluor 780, PerCP-eFluor 710, eFluor 710) are conventional fluorochromes. In contrast, the eVolve line of products are Quantum dots.

Are the eFluor Organic Dyes photo-labile?

As with other fluorochromes, we recommend minimal exposure to light to maintain optimal signal.
