SPCC1840.08c Antibody is a polyclonal antibody specifically developed for detection of the SPCC1840.08c protein in Schizosaccharomyces pombe (strain 972 / ATCC 24843), commonly known as fission yeast . This antibody is raised in rabbit using recombinant Schizosaccharomyces pombe SPCC1840.08c protein as the immunogen . The target protein has a UniProt accession number of O74481, which can be used for further reference in protein databases . As a research tool, SPCC1840.08c Antibody enables the study of protein expression and function in this model organism, which is widely used in molecular and cellular biology research.
The SPCC1840.08c Antibody has been specifically tested and validated for the following applications:
| Application | Validation Status |
|---|---|
| ELISA | Validated |
| Western Blot (WB) | Validated |
These applications have been specifically tested to ensure identification of the target antigen . Unlike some other antibodies that may have broader application profiles (such as the CCDC85B antibody which is validated for WB, IHC, IF/ICC, IP, and ELISA ), the SPCC1840.08c Antibody has a more focused application range specifically for protein detection in Schizosaccharomyces pombe research contexts.
The SPCC1840.08c Antibody requires careful storage to maintain its activity and specificity. The recommended storage conditions are:
These storage recommendations align with general best practices for antibody preservation. Similar to other research antibodies, proper aliquoting upon receipt is advisable to minimize freeze-thaw cycles. The antibody is provided in a liquid form with a storage buffer containing 50% glycerol, 0.01M PBS at pH 7.4, and 0.03% Proclin 300 as a preservative .
Ensuring specificity when working with SPCC1840.08c Antibody requires attention to several methodological factors:
The SPCC1840.08c Antibody is an antigen affinity-purified polyclonal antibody, which means it contains a heterogeneous mixture of antibodies that recognize different epitopes on the target protein . While this can provide robust signal detection, it may also introduce background in some experimental contexts. To optimize specificity:
Include appropriate negative controls, such as:
Optimize antibody dilution specifically for each experimental setup and detection method. Unlike monoclonal antibodies that tend to have more consistent dilution requirements, polyclonal antibodies like SPCC1840.08c may require empirical optimization.
Consider pre-adsorption against related proteins if working in complex samples where cross-reactivity might be an issue.
Researchers should note that this antibody has been specifically validated for Schizosaccharomyces pombe (strain 972 / ATCC 24843) and may not show reactivity with other yeast species or more distantly related organisms .
When optimizing Western Blot protocols with SPCC1840.08c Antibody, several technical considerations should be addressed:
Sample preparation:
Proper cell lysis and protein extraction from S. pombe requires specialized protocols due to the robust cell wall
Consider spheroplasting of S. pombe cells prior to lysis, similar to methodologies used in other S. pombe protein studies
Include protease inhibitors to prevent degradation of the target protein
Blocking conditions:
Detection system selection:
Technical validation:
Unlike some antibodies with well-established dilution recommendations (like CCDC85B antibody with recommendations of 1:200-1:1000 for Western Blot ), optimal dilutions for SPCC1840.08c Antibody may need to be determined empirically for each experimental system.
Non-specific binding is a common challenge when working with polyclonal antibodies like SPCC1840.08c. Several methodological approaches can help minimize this issue:
Stringent washing protocols:
Increase washing duration and/or number of washes
Consider using washing buffers with slightly increased detergent concentration (0.1-0.5% Tween-20)
Ensure complete coverage of membranes/plates during washing steps
Antibody dilution optimization:
Cross-adsorption techniques:
Pre-incubation of diluted antibody with non-specific proteins
Use of commercially available blocking reagents specifically designed for polyclonal antibodies
Buffer optimization:
When comparing results with those obtained using other antibodies, researchers should be aware that detection methodologies may differ significantly, as seen in comparative studies of other antibodies like PD-L1 antibodies (SP142 and 22C3) which showed significant differences in staining patterns and sensitivities .
Inclusion of appropriate controls is critical for reliable interpretation of results when using SPCC1840.08c Antibody:
Positive controls:
Negative controls:
Loading/technical controls:
Specificity validation:
Peptide competition assays using recombinant SPCC1840.08c protein
Comparison with alternative detection methods (e.g., mass spectrometry) where feasible
When using SPCC1840.08c Antibody for quantitative analysis, several methodological considerations apply:
Standard curve generation:
Use purified recombinant SPCC1840.08c protein at known concentrations
Ensure the standard curve covers the expected range of protein expression
Apply appropriate curve-fitting algorithms (linear, four-parameter logistic, etc.)
Normalization strategies:
Normalize to total protein concentration
Use internal reference proteins with stable expression in S. pombe
Consider the limitations of housekeeping proteins as normalizers in different experimental conditions
Technical replication:
Perform at least three technical replicates for each biological sample
Calculate coefficients of variation to assess reproducibility
Exclude outliers based on pre-established statistical criteria
Analytical considerations:
Define the lower limit of detection and quantification
Establish the dynamic range of the assay with this specific antibody
Account for potential hook effects at high protein concentrations
Unlike immunohistochemical scoring systems used with antibodies like 22C3 and SP142 for PD-L1 analysis , quantification with SPCC1840.08c Antibody in biochemical assays typically relies on direct signal intensity measurement rather than percentage-based scoring systems.
While SPCC1840.08c Antibody has been specifically validated for Schizosaccharomyces pombe (strain 972 / ATCC 24843) , researchers may consider its application in additional experimental contexts with appropriate validation:
Alternative S. pombe strains:
Validation would be required for strains other than 972 / ATCC 24843
Sequence conservation of the target protein should be verified
Western blot confirmation of specificity is recommended prior to other applications
Immunoprecipitation potential:
Though not explicitly validated for immunoprecipitation , polyclonal antibodies often perform well in this application
Optimization of binding conditions, bead selection, and elution protocols would be necessary
Pre-clearing samples and using appropriate negative controls becomes particularly important
Subcellular localization studies:
If considering this antibody for immunofluorescence applications, extensive validation would be required
Fixation method optimization would be critical (alcohols, aldehydes, etc.)
Signal amplification systems might be necessary depending on target abundance
Cross-species applications:
While not recommended without thorough validation, sequence homology analysis between S. pombe SPCC1840.08c and proteins from related species could identify potential cross-reactivity
Progressive epitope mapping would be beneficial for determining specificity boundaries
When expanding applications beyond those explicitly validated, researchers should follow similar rigorous validation protocols as seen in comparative antibody studies , including side-by-side testing with alternative detection methods.
