製品の詳細Rat monoclonal [YL1/2] to Tubulin - Loading Control
The YL1/2 monoclonal has been reported in the literature to recognise tyrosinated alpha tubulin but can also bind other targets that contain a negatively charged carboxy terminus such as recA and oxidized actin (PubMed IDs: 6811596, 6415068, 6204858). The amino acid sequence Glu-Glu-Phe (EEF) has been used as a carboxy terminus tag to purify proteins using the YL1/2 monoclonal (PubMed IDs: 1710580, 1713577).

一次抗体 備考This antibody can be used as a loading control on Western blots (Allen et al.) and is not detected by anti-mouse Ig secondaries. It has been used in epitope tagging procedures to detect proteins tagged with a C-terminal Gly-Gly-Phe(OH) epitope. Under some circumstances this antibody may cross-react with other protein including E. coli rec A and oxidized actin.

機能Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha-chain.
配列類似性Belongs to the tubulin family.
翻訳後修飾Undergoes a tyrosination/detyrosination cycle, the cyclic removal and re-addition of a C-terminal tyrosine residue by the enzymes tubulin tyrosine carboxypeptidase (TTCP) and tubulin tyrosine ligase (TTL), respectively.
Some glutamate residues at the C-terminus are polyglutamylated. This modification occurs exclusively on glutamate residues and results in polyglutamate chains on the gamma-carboxyl group. Also monoglycylated but not polyglycylated due to the absence of functional TTLL10 in human. Monoglycylation is mainly limited to tubulin incorporated into axonemes (cilia and flagella) whereas glutamylation is prevalent in neuronal cells, centrioles, axonemes, and the mitotic spindle. Both modifications can coexist on the same protein on adjacent residues, and lowering glycylation levels increases polyglutamylation, and reciprocally. The precise function of such modifications is still unclear but they regulate the assembly and dynamics of axonemal microtubules.
Acetylation of alpha-tubulins at Lys-40 stabilizes microtubules and affects affinity and processivity of microtubule motors. This modification has a role in multiple cellular functions, ranging from cell motility, cell cycle progression or cell differentiation to intracellular trafficking and signaling.

ICC/IF image of ab6160 stained HeLa (Human epithelial cell line from cervix adenocarcinoma) cells.
The cells were fixed in 100% methanol 5 minutes, permeabilized with 0.1% Triton X-100 for 5 minutes and then incubated in 1% BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1 hour to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab6160, 1/1000 dilution) overnight at +4°C. The secondary antibody (green) was ab150165 Alexa Fluor® 488 goat anti-rat IgG (H+L) pre-adsorbed, used at a 1/1000 dilution for 1 hour. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
The negative control (inset) is a secondary-only assay to demonstrate low non-specific binding of the secondary antibody.
This product also gave a positive signal under the same testing conditions in HeLa cells fixed with 4% formaldehyde (10 minutes).

Cytoskeleton and major extracellular matrix proteins in human DPSC (Dental pulp stem cell) were analyzed by immunofluorescence.
Vimentin and tubulin (Panel D, control, E, (BD) and F, (BR)) are shown.
After 7 days in contact with/without the materials (Biodentine (BD) and Bioroot (BR)), coated coverslip cultures were fixed in PBS (pH 7.4) containing 4% paraformaldehyde/5% sucrose for 10 minutes. For detection of intracellular molecules, the cells on the coverslips were permeabilized using 0.5% Triton X-100. To block background staining, cells were treated with PBS containing 1% BSA/1% glycine at 37°C for 20 minutes. Samples were incubated with the primary antibody at 4°C overnight or at 37°C for 2 hours. For double immunostaining, primary antibodies were incubated as above. Samples were then incubated with the appropriate secondary antibodies at 37°C for 1 hour. Cell nuclei were stained using DAPI.

Egr3 localization is associated with microtubule organization in mouse oocytes.
Mouse oocytes stained for Tubulin using ab6160 (Right panels, red) in ICC/IF.
The localization of Egr3 and microtubule at thawing of vitrified oocytes. Vitrified MII oocytes were stored in LN2 for 2 weeks. Oocytes were taken out from LN2, incubated in decreasing concentrations of sucrose, and then fixed immediately. These oocytes were subjected to immunofluorescence staining with anti-Egr3 and ab6160 antibodies. Arrows indicate the growing arrays of microtubules at the site of Egr3 accumulation.
Red: Microtubule (MT).
IHC image of Tubulin staining in human colon formalin fixed paraffin embedded tissue section*, performed on a Leica Bond™ system using the standard protocol F.
The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer pH 6 for 20 minutes. The section was then incubated with ab6160, 5 µg/ml, for 15 minutes at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
