Thy 1 antibody

Manufactured by Santa Cruz Biotechnology

The Thy-1 antibody is a protein that binds to the Thy-1 cell surface antigen. It is commonly used in research applications to identify and isolate Thy-1 positive cells, which are often associated with certain cell types and developmental stages.

Example 6

Since substance P of KLD12-SP is expected to have the ability to mobilize mesenchymal stem cells, immunofluorescent staining was performed using CD90 (Thy-1 antibody, Santa Cruz Biotechnology) and CD105 (anti-endoglin monoclonal antibody, Millipore, Temecula, Calif.), which are markers specifically expressed in mesenchymal stem cells, in the groups treated with KLD12-SP-MSC and KLD12-SP without MSC. Alexa Fluor 594 donkey anti-rabbit IgG (Invitrogen) and Alexa Fluor 488 goat anti-mouse IgG (Invitrogen) were used as secondary antibodies and counterstained with DAPI to observe cell nuclei. The results are shown in Fig.

As shown in FIG. 8, the expression of CD90 and CD105, which are mesenchymal stem cell markers, was at least twice that of the control group in the group treated with KLD12-SP without MSC. These results indicate that KLD12-SP has the ability to mobilize mesenchymal stem cells to the arthritic sites, and it was determined that the regeneration of chondrocytes can be performed more actively by the mesenchymal stem cells migrating to the arthritic sites.

Lysates of cultural cells (BMSCc and MCF7) and tissues (mouse brain at postnatal day 1 and adult rat DRGs) were extracted using 1× RIPA buffer (20 mm Tris–HCl pH 7.4, 150 mm NaCl, 1% Nonidet P-40, 1% sodium deoxycholate, 0.1% SDS, with 0.1% Triton X100 and protease inhibitor cocktail). Protein concentration was determined by using the BCA kit (Pierce, Rockford, IL). Western blotting (20 μg protein) was preceded by SDS-PAGE gel electrophoresis, transferred onto nitrocellulose, and probed with Thy-1 antibody (1:100, Santa Cruz Biotechnology, SCB, Santa Cruz, CA) and Stro1 antibody (1:100, Life Technologies). Immunoreactive proteins were detected by enhanced chemiluminescence (Pierce, Rockford, IL) after incubation with HRP-conjugated second antibodies (1:2000, SCB) and exposed to photographic film. GAPDH (1:2000, Cell Signaling, Danvers, MA) was used as a loading control.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
