- SPAG4
- Lot Number
- 3522
- Method validated
- Western Blotting
- Positive Control
- NIH/3T3 mouse embryonic fibroblast cells overexpressing HA- and myc-tagged SPAG4
- Negative Control

- Primary Antibody
- ABIN4368846
- Secondary Antibody
- anti-mouse IgG, HRP-linked (Sigma A9044, Lot 034M4761)
- Full Protocol
- NIH/3T3 cells (ATCC, CRL-1658) are grown in DMEM+GlutaMAX (Gibco, 31966-021, Lot 1852045) supplemented with fetal bovine serum (Gibco 270-106) and Pen/Strep (Gibco 15140), at 37°C and 5% CO2 to 70% confluency.
- Transfect cells with HA/myc-tagged SPAG4 expression plasmid or HA/myc-tagged SPAG4L-2 (Frohnert et al., 2011) expression plasmid using EndofectinMax (GeneCopoeia) following the manufacturer´s instructions.
- Grow cells for 24h.
- Lyse cells in SDS-sample buffer and denature total cellular lysates for 5min at 95°C.
- Separate cell lysates on a denaturing 10% SDS-PAGE gel (Laemmli 1970).
- Transfer proteins onto 0.2 µm Protran membrane (GE Healthcare, 10600004, A10043108) with a Western blotting system for 1h at 400mA (Towbin et al., 1979).
- Block the membrane in TBST (50mM Tris-HCl, pH7.4, 150mM NaCl, 0.2% Tween 20) containing 5% milk (blocking solution) for 60min at RT.
- Incubate membrane with primary rabbit anti-Sperm Associated Antigen 4 (SPAG4) antibody (antibodies-online, ABIN4368846, lot 3522) diluted 1:1000 in blocking solution ON at 4°C.
- Wash membrane with TBST for 30min at RT.
- Incubate membrane with secondary goat anti-rabbit IgG (H+L), HRP-linked (Jackson Immuno Research, 111-035-003, lot 123450) diluted 1:4000 in blocking solution for 45min at RT.
- Wash membrane 6x for 5 min with TBST.
- Reveal protein bands using Clarity Max Western ECL substrate (Bio-Rad, 1705062) and capture images via Chemidoc Imaging System (BioRad).
- Incubate membrane with primary mouse anti-myc tag antibody (clone 9E10) diluted 1:50 in blocking solution ON at 4°C.
- Wash membrane with TBST for 30min at RT.
- Incubate membrane with secondary anti-mouse IgG, HRP-linked (Sigma A9044, Lot 034M4761) diluted 1:5000 in blocking solution for 45min at RT.
- Reveal protein bands using Clarity Max Western ECL substrate (Bio-Rad, 1705062).
- Experimental Notes
- ABIN4368846 passes validation when used for detection of ectopically expressed proteins. However, it reacted with proteins specifically present in testicular tissue from day 7 post-partum to the adult and even in Spag4-deficient testis (Spag4-deficiency was verified by genotyping and RT-PCR on testis cDNA).

- Full Protocol

- Image acquisition on Zeiss LSM 510 confocal microscope and processsing using Adobe Photoshop 5.0.
- Experimental Notes
An anti-myc antibody (red) detected both myc-tagged proteins, but anti the SPAG4 antibody ABIN4368846 (green) exclusively detected SPAG4 without any cross-reaction to SPAG4L-2. ABIN4368846 detected SPAG4 at the nuclear membrane, as expected.
However, on mouse testicular cells ABIN4368846 decorated the manchette in spermatids (as was expected) but gave a much more intense signal on cells, that do not express Spag4 (Pasch et al., 2015)

- 注意事项
- WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
