The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/400. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
Use at an assay dependent concentration.
Use a concentration of 1 µg/ml. Detects a band of approximately 47 kDa (predicted molecular weight: 47 kDa).
功能ATP-dependent RNA helicase which is a subunit of the eIF4F complex involved in cap recognition and is required for mRNA binding to ribosome. In the current model of translation initiation, eIF4A unwinds RNA secondary structures in the 5'-UTR of mRNAs which is necessary to allow efficient binding of the small ribosomal subunit, and subsequent scanning for the initiator codon.
序列相似性Belongs to the DEAD box helicase family. eIF4A subfamily. Contains 1 helicase ATP-binding domain. Contains 1 helicase C-terminal domain.

Paraffin embedded human duodenum tissue was incubated with ab31218 (1/400 dilution) for 30 mins at room temperature. Antigen retrieval was performed by heat induction in citrate buffer pH 6.
ab31218 was tested in a tissue microarray (TMA) containing a wide range of normal and cancer tissues. Further results for this antibody can be found at www.proteinatlas.org
Mineralocorticoid Receptor was immunoprecipitated using 0.5mg Mouse skeletal muscle whole tissue extract, 5µg of Rabbit polyclonal to Mineralocorticoid Receptor and 50µl of protein G magnetic beads (+). No antibody was added to the control (-). The antibody was incubated under agitation with Protein G beads for 10min, Mouse skeletal muscle whole tissue extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation. Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab31218. Secondary: Mouse monoclonal [SB62a] Secondary Antibody to Rabbit IgG light chain (HRP) (ab99697). Band: 47kDa: Mineralocorticoid Receptor.
