Full Methods

Primary Antibody: ABIN749093

Secondary Antibody: Donkey-anti-Rabbit-Cy3

Full Protocol:

• Tumor cell transplanted mouse brain was dissected, fixed in 4% PFA for overnight, saturated in 30% sucrose, mounted in Cryo, and sectioned into 12µm sections.
• Immunostaining for Cryo Sections:
• Dry slides at 50-55°C for 15-30 min (or RT for 30min)
• Wash three times with PBS 5min (shake gently)
• Block with 10% Normal Donkey Serum (NDS) at RM for 1hour
• Incubate with primary antibody at 4°C overnight (Prepared in 2% NDS)
• Rabbit-anti-Osteoactivin antibody (ABIN749093) diluted 1:50-1:400
• Wash three times with PBS 5min (shake gently)
• Incubate with secondary antibody together with DAPI at RT for 1h (Prepared in 2% NDS), cover the chamber with foil
• Donkey-anti-Rabbit-Cy3
• DAPI 1:100
• Wash three times with PBS 5min (shake gently)
• Add three drops of water-based Immu-mount
• Cover with 24x60 cover glass
• Imaging
• Images were taken using a Zeiss Axio2-Imaging system, 20X-0.5NA-Dry Dye-1004-072 objective, DAPI and Cy3 channel.

Experimental Notes: ABIN749093 worked within the diution range 1:50 - 1:200; the antibody did not work well at a 1:400 dilution.

Target Details for Osteoactivin

Target: Osteoactivin (GPNMB)

Alternative Name: GPNMB

Background:

Synonyms: NMB, HGFIN, Transmembrane glycoprotein NMB, Transmembrane glycoprotein HGFIN, GPNMB, UNQ1725/PRO9925

Background: The protein encoded by this gene is a type I transmembrane glycoprotein which shows homology to the pMEL17 precursor, a melanocyte-specific protein. GPNMB shows expression in the lowly metastatic human melanoma cell lines and xenografts but does not show expression in the highly metastatic cell lines. GPNMB may be involved in growth delay and reduction of metastatic potential. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq].
