Target Information

Target informationPurine rich element binding protein B (PURB), also known as Pur beta, is a sequence specific nucleic acid binding protein encoded by the PURB gene. It belongs to the PUR protein family and is commonly described in relation to purine rich single stranded DNA and RNA binding. PURB is often referenced alongside its closely related family member PURA, but it is a distinct target with its own gene identity and molecular features. MtoZ Biolabs offers the IP-MS Validated PURB Polyclonal Antibody as an IP-MS validated antibody for selective PURB enrichment and downstream protein mass spectrometry studies. This IP-MS validated PURB Polyclonal Antibody supports workflows requiring a PURB antibody validated by IP-MS, including use as a PURB IP antibody for immunoprecipitation, target capture, and protein interaction analysis. It is well suited for researchers seeking a PURB antibody for immunoprecipitation and a PURB antibody in IP-MS workflows designed to examine PURB-associated complexes and mass spectrometry based target identification.

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 levelIncluded validationBest for
IP-MS OnlyConfirms target-specific enrichment by immunoprecipitation followed by mass spectrometry analysis.IP-based protein enrichment and target specificity assessment.
Western Blot OnlyConfirms target detection by Western blot under defined experimental conditions.Routine target detection and expression-level assessment.

MtoZ Biolabs IP-MS Antibody Solutions

Traditional Antibody Supplier

Conventional workflow
  • Customers need to purchase small amounts of antibody for in-house testing

    01
  • Validation depends on customer-provided samples and workflows

    02
  • Suppliers usually stop support after product delivery

    03
  • Customers must find a separate provider for MS or interaction analysis

    04
  • Higher risk of repeated trial-and-error

FAQ

IP-MS validation means that the antibody is first used to pull down proteins from a cell lysate, and the captured proteins are then analyzed by mass spectrometry. This helps confirm whether the antibody can recognize and enrich its intended target protein, instead of mainly pulling down unrelated background proteins.
IP-MS validation does not require a long additional wait. Based on our optimized workflow, it typically adds no more than 5 to 7 business days to the standard processing time. After validation is completed, the antibody and validation report are delivered together.
The validation report includes key experimental records, workflow details, antibody usage information, mass spectrometry settings, target protein identification results, and signal intensity evaluation. The report provides clear supporting data that customers can review and use for project documentation.
We use an ultra-high resolution mass spectrometry platform for IP-MS validation. This platform supports accurate protein identification and provides reliable peptide-level evidence for reviewing antibody validation results.
