Target Information
| Target information | DNA-directed RNA polymerase subunit H (POLR2H), also known as RPB8, is a conserved shared subunit of eukaryotic RNA polymerases I, II, and III. POLR2H contributes to core transcription machinery and is closely associated with RNA synthesis, polymerase assembly, and nuclear gene expression regulation. Its presence across multiple RNA polymerase complexes makes POLR2H a useful protein for studies of transcriptional machinery and polymerase biology. For RNA polymerase-related protein studies, MtoZ Biolabs offers IP-MS Validated POLR2H Antibody for immunoprecipitation-based enrichment before downstream mass spectrometry analysis. As a POLR2H antibody validated by IP-MS, this product supports users seeking a POLR2H IP antibody, a POLR2H antibody for immunoprecipitation, or a POLR2H antibody in IP-MS workflows. It can support target capture, POLR2H-associated protein analysis, and LC-MS/MS-based characterization in transcription machinery research. |

Antibody Validation Levels
To support different research goals, budgets, and evidence requirements, our antibodies are available with multiple validation levels. Each antibody undergoes IP-MS validation before delivery to confirm target-specific recognition and enrichment. For projects requiring additional confirmation, Western blot validation can be added to provide orthogonal evidence of target detection.
| Validation level | Included validation | Best for |
|---|---|---|
| IP-MS Only | Confirms target-specific enrichment by immunoprecipitation followed by mass spectrometry analysis. | IP-based protein enrichment and target specificity assessment. |
| Western Blot Only | Confirms target detection by Western blot under defined experimental conditions. | Routine target detection and expression-level assessment. |
| IP-MS + Western Blot | Combines mass spectrometry-based target enrichment evidence with Western blot-based detection evidence. | Customers requiring more comprehensive validation support. |
