TUBE1, also known as Epsilon-tubulin or Tubulin epsilon chain, is a member of the tubulin protein family involved in cellular structure and microtubule organization . Unlike the more extensively characterized alpha and beta tubulins, epsilon tubulin has distinct functions in microtubule nucleation and organization. The protein has a calculated molecular weight of approximately 52,932 Da according to technical specifications .
Current research-grade TUBE1 monoclonal antibodies have been validated for multiple applications including:
Each antibody should be individually optimized for specific experimental conditions to ensure optimal results .
Most commercially available TUBE1 monoclonal antibodies demonstrate reactivity against human, mouse, and rat species . For example, the monoclonal antibody with clone number 2B3 (IgG isotype) shows confirmed reactivity to TUBE1 across these three species .
For optimal Western blotting results with TUBE1 monoclonal antibodies:
Recommended dilution ranges typically fall between 1:1000-1:2000 or 1:500-1:5000 depending on the specific antibody clone
Validation data indicates successful detection in MCF7 cell lysates as a positive control
The expected band size corresponds to the calculated molecular weight of approximately 53 kDa
Standard Western blotting protocols apply, with attention to proper blocking and washing steps
Researchers should verify specific band detection before proceeding with experimental analyses.
Proper validation should include:
Specificity testing: Verification using known positive samples (e.g., MCF7 cells for certain antibodies)
Signal verification: Confirmation of appropriate molecular weight bands in Western blot applications
Cross-reactivity assessment: Testing against potential cross-reactive proteins, particularly other tubulin family members
Immunogen verification: Understanding the specific peptide sequence used for antibody generation (synthetic peptides of Epsilon Tubulin are common immunogens)
Batch testing: Verifying consistency between different lots of the same antibody
Most TUBE1 monoclonal antibodies require:
Storage in buffers containing stabilizers (typically PBS with 50% glycerol, 0.5% BSA, and 0.02% sodium azide)
Long-term storage at recommended temperatures (typically -20°C)
Minimal freeze-thaw cycles to preserve antibody integrity
Protection from contamination and degradation
Recent advances in recombinant antibody technology offer significant advantages for TUBE1 research:
Production methods can generate high-yield recombinant monoclonal antibodies from human HEK293 suspension cultures, addressing concerns with reproducibility, costs, and ethical issues associated with animal-derived antibodies
The protocol involves:
Generating antibody heavy and light chain plasmids from a primary sequence
Transfecting plasmids into cells
Purifying antibodies using cost-effective methods
This approach yields consistent antibodies with potentially increased experimental flexibility
Researchers can introduce sequence modifications to enhance specificity for TUBE1 over other tubulin family members
Optimal purification methodologies include:
Affinity chromatography: TUBE1 antibodies can be effectively purified from mouse ascites or cell culture supernatants using affinity chromatography with specific immunogens
Column-based techniques: These provide high purity while maintaining antibody activity
Low-cost approaches: As described in recent literature, cost-effective purification methods can produce high-yield reagents suitable for research applications
When selecting between tubulin family antibodies:
Alpha and beta tubulin antibodies (such as Anti-β-Tubulin mouse monoclonal antibodies) are more commonly used for general cytoskeletal studies
TUBE1 antibodies target epsilon tubulin specifically and serve more specialized research purposes
Many researchers using tubulin antibodies also investigate related products such as:
TUBE1 monoclonal antibodies typically:
Target synthetic peptide sequences specific to Epsilon Tubulin
Require careful epitope selection to avoid cross-reactivity with other tubulin family members
May utilize specific regions of the protein that differ from the highly conserved domains shared across the tubulin family
While not specific to TUBE1, monoclonal antibody research is advancing in chronic pain treatment:
Monoclonal antibodies target specific molecules involved in pain signaling pathways, offering novel therapeutic approaches
Current targets include tumor necrosis factor (TNF), nerve growth factor (NGF), calcitonin gene-related peptide (CGRP), and interleukin-6 (IL-6)
These approaches are being investigated for conditions including osteoarthritis, chronic lower back pain, migraine, and rheumatoid arthritis
Preclinical research suggests potential for additional targets in pain processing pathways
Recent structural analysis of neutralizing monoclonal antibodies provides insights applicable to TUBE1 research:
Binding characteristics can be determined through site-directed alanine mutations of potential epitope residues
ELISA testing of mutant antigens can identify key contact residues
Complementarity determining regions (CDRs) of antibody heavy and light chains interact with specific protein loops to create binding footprints
Buried surface area measurements provide quantitative data on antibody-antigen interaction strength
To minimize non-specific binding:
Optimize blocking conditions using appropriate blocking agents (BSA, non-fat milk, or commercial blockers)
Titrate antibody concentrations to determine optimal signal-to-noise ratios
Increase washing stringency in immunoassay protocols
Consider using monoclonal antibodies with more defined epitope specificity
Implement negative controls lacking primary antibody to identify sources of background
Essential controls include:
Positive controls: Cell lines known to express TUBE1 (e.g., MCF7 cells for some antibody clones)
Negative controls: Samples known to have minimal TUBE1 expression or knockout/knockdown models
Isotype controls: Matched isotype antibodies to control for non-specific binding
Secondary antibody-only controls: To identify background from detection systems
Peptide competition assays: Using immunizing peptides to confirm specificity
