Target Information
| Target information | DnaJ homolog subfamily B member 11 (DNAJB11), also known as ERdj3 or HEDJ, is an endoplasmic reticulum co-chaperone of the Hsp40 family. Through its functional relationship with HSPA5/BiP, DNAJB11 is commonly studied in secretory and membrane protein folding, ER quality control, ER stress response, and proteostasis. For ER proteostasis and secretory pathway studies, MtoZ Biolabs offers IP-MS Validated DNAJB11 Polyclonal Antibody for DNAJB11 enrichment prior to LC-MS/MS analysis. This DNAJB11 antibody validated by IP-MS may be used as a DNAJB11 IP antibody or DNAJB11 antibody for immunoprecipitation. It can also be incorporated as a DNAJB11 antibody in IP-MS workflows involving ER-associated protein quality control. |

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. |
