MRPS24 (Mitochondrial Ribosomal Protein S24) is a component of the mitochondrial ribosomal small 28S subunit that participates in protein synthesis within the mitochondrion . It has a calculated molecular weight of 19 kDa (167 amino acids) but is typically observed at 15-19 kDa in experimental conditions . The protein is significant in research because it plays a critical role in mitochondrial translation, which is essential for synthesizing proteins that form the oxidative phosphorylation system . Recent studies have also identified MRPS24 as potentially important in cancer research, particularly in lung adenocarcinoma, where its expression correlates with prognosis, tumorigenesis, genetic alterations, and immune cell infiltration . Understanding MRPS24 function provides insights into both basic mitochondrial biology and disease mechanisms.

What applications are MRPS24 antibodies validated for?

MRPS24 antibodies have been validated for several key research applications, with varying recommended dilutions for optimal results. The primary applications include Western Blot (WB) with recommended dilutions of 1:200-1:1000, Immunohistochemistry (IHC) with recommended dilutions of 1:200-1:800, and ELISA . Western blotting has been documented in multiple peer-reviewed publications, confirming the antibody's reliability for this application . For immunohistochemistry, MRPS24 antibodies have been successfully used on human tissues including stomach tissue, tonsil, and cervical cancer samples . It's important to note that optimal dilutions may vary depending on the specific experimental conditions, sample type, and detection method, necessitating optimization for each experimental system.

How should researchers prepare samples for MRPS24 antibody detection?

For optimal MRPS24 antibody detection, sample preparation varies by application method. When performing Western blot analysis, researchers should extract proteins from tissues or cell lines (such as HepG2 cells, which have shown positive detection) . Tissue lysis should be performed using buffers containing protease inhibitors to prevent protein degradation. For immunohistochemistry, the search results indicate that antigen retrieval is a critical step, with suggested protocols using either TE buffer at pH 9.0 (preferred) or citrate buffer at pH 6.0 as an alternative . Fixed tissue sections should be deparaffinized and rehydrated before antigen retrieval. Blocking with appropriate serum (typically 5-10% normal serum from the same species as the secondary antibody) for 1 hour at room temperature is recommended to minimize non-specific binding. For both applications, researchers should include positive controls (HepG2 cells for WB, human stomach tissue for IHC) and negative controls (omitting primary antibody) to validate results .

What are the recommended storage conditions for MRPS24 antibodies?

MRPS24 antibodies require specific storage conditions to maintain their functionality and prevent degradation over time. According to the product information, these antibodies should be stored at -20°C, where they remain stable for approximately one year after shipment . The antibodies are typically supplied in a storage buffer consisting of PBS with 0.02% sodium azide and 50% glycerol at pH 7.3, which helps maintain stability . For small volume antibodies (20μl), manufacturers may include 0.1% BSA in the formulation for additional stabilization . While some suppliers indicate that aliquoting is unnecessary for -20°C storage, it is generally good laboratory practice to aliquot antibodies upon first thawing to avoid repeated freeze-thaw cycles that can compromise antibody performance . When shipping is required, antibodies should be transported on ice packs and stored immediately at the recommended temperature upon receipt .

How can researchers validate the specificity of MRPS24 antibodies in their experimental systems?

Validating MRPS24 antibody specificity requires a multi-approach strategy to ensure reliable research outcomes. Researchers should first perform Western blot analysis to confirm that the detected protein appears at the expected molecular weight range of 15-19 kDa . Additional validation can be accomplished by including positive controls such as HepG2 cells, which have demonstrated reliable MRPS24 expression . For definitive validation, researchers should consider knockdown or knockout experiments using siRNA, shRNA, or CRISPR-Cas9 techniques targeting MRPS24, which should result in reduced or absent antibody signal if the antibody is specific . Another robust validation approach is to perform immunoprecipitation followed by mass spectrometry to confirm the identity of the pulled-down protein. For immunohistochemistry applications, researchers should compare staining patterns with published MRPS24 localization data and perform parallel experiments with alternative MRPS24 antibodies from different manufacturers or those recognizing different epitopes . Finally, testing the antibody across multiple species (human and mouse tissues are documented to work) can provide additional evidence of specificity based on evolutionary conservation of the protein .

How do researchers troubleshoot inconsistent MRPS24 antibody staining patterns in immunohistochemistry?

Inconsistent staining patterns in MRPS24 immunohistochemistry can arise from multiple sources and require systematic troubleshooting. The first step is to optimize antigen retrieval conditions, as the recommended protocols suggest testing both TE buffer at pH 9.0 and citrate buffer at pH 6.0 to determine which provides optimal epitope exposure for specific tissue types . Antibody concentration must be carefully titrated; while recommended dilutions range from 1:200 to 1:800 for IHC, researchers should perform dilution series experiments (e.g., 1:100, 1:200, 1:400, 1:800) to identify the optimal concentration for their specific tissue samples . Fixation variables significantly impact staining quality – overfixation can mask epitopes while underfixation may result in tissue degradation; therefore, researchers should standardize fixation protocols (typically 24 hours in 10% neutral buffered formalin) and document fixation times. Detection system sensitivity should be evaluated by comparing different visualization methods (e.g., DAB versus AEC chromogens, or amplification systems like tyramide signal amplification). Background staining can be reduced by extending blocking steps (60 minutes with 5-10% serum) and including additional blocking agents such as 0.3% hydrogen peroxide to block endogenous peroxidase activity. Finally, researchers should validate results by comparing staining patterns across multiple MRPS24 antibodies and confirming subcellular localization is consistent with expected mitochondrial distribution .
