Protokoll

Primärantikörper: ABIN2855596

Sekundärantikörper: goat anti-rabbit AF488-conjugated antibody (Invitrogen by Thermo Fisher Scientific, A11034, lot 1971418)

Full Protocol:

• Obtain dog samples after autopsy and immersion-fix in buffered formaldehyde for 16h.
• Perfuse mice with paraformaldehyde 4% in 0.1M phosphate buffer pH 7.4 and post-fix in the same fixative for an additional 2h at RT.
• Wash, dehydrate, and embed samples in paraffin wax.
• Cut with a microtome into 6µm sections and mount on glass slides.
• After paraffin removal, process sections by microwave antigen retrieval for 10min (95-100°C) in 10mM sodium citrate buffer (pH 6.0).
• Let sections cool for 10min.
• Wash sections under running water for 5-10min.
• Wash sections 2x 5min with distilled water.
• Wash sections 5min with 0.01M PBS.
• Incubate sections in PBS containing 1% albumin from chicken egg white (Sigma, A5378) for 1h at RT to block non-specific binding sites.
• Incubate sections with primary rabbit anti-Calretinin antibody (antibodies-online, ABIN2855596, lot 39876) diluted 1:200 in PBS-BSA-PLL at 4°C.
• Wash sections 3x 5min with 0.01M PBS.
• Incubate sections with secondary goat anti-rabbit AF488-conjugated antibody (Invitrogen by Thermo Fisher Scientific, A11034, lot 1971418) diluted 1:500 in 0.1M PBS for 1h at RT.
• Wash sections 3x 5min with 0.01M PBS.
• Mount specimens in Fluoroshield (Sigma, F6182, lot MKCB0153V).
• Acquire images with a fluorescence microscope and appropriate filter settings for AF488, e.g. Leica DM 6000B fluorescence microscope equipped with the manufacturer’s FITC filter set and digital camera at magnifications of 20x, 40x, and 63x. Parameters for image acquisition (Exposure 2.2s, Gain 2.3x, Saturation 1.5, Gamma 1.10) unchanged for all images.

Anmerkungen:

For the incubation with the primary antibody ABIN2669973 1:100, 1:500, and 1:1000 dilutions were also tested.

Target: Calretinin (CALB2) (Calbindin 2 (CALB2))

Andere Bezeichnung: calbindin 2

Hintergrund: This gene encodes an intracellular calcium-binding protein belonging to the troponin C superfamily. Members of this protein family have six EF-hand domains which bind calcium. Three alternatively spliced transcript variants that encode different proteins have been described.
