Overview

  • Product nameAnti-Calpain 2 antibody
    See all Calpain 2 primary antibodies
  • Description
    Rabbit polyclonal to Calpain 2
  • Specificityab39165 binds to reduced and non-reduced calpain 2, but does not cross react with the other calpain family members (m calpain, calpain 94, ncl 2, ncl 3, etc.). It reacts with latent and active (amino-truncated) Calpain 2.
  • Tested applicationsSuitable for: WB, ICC/IF, IHC-Pmore details
  • Species reactivity
    Reacts with: Mouse, Rat, Human
  • Immunogen

    Synthetic peptide based on the amino terminal end of domain-III in the large subunit of Rat Calpain 2. (Peptide available as ab41302.)

  • Positive control
    • Cell lysate from human chondrosarcoma treated with IL1 alpha.

Properties

Applications

Our Abpromise guarantee covers the use of ab39165 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB 1/1000 - 1/5000. Detects a band of approximately 76 kDa (predicted molecular weight: 80 kDa). Dilution optimised using Chromogenic detection.
ICC/IF Use at an assay dependent concentration. PubMed: 17192410
IHC-P Use a concentration of 4 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.

    Predicted band size : 80 kDa
    Observed band size : 76 kDa (why is the actual band size different from the predicted?)
  • ab39164 (4µg/ml) staining CALPAIN2 in human lung using an automated system (DAKO Autostainer Plus). Using this protocol there is cytoplasmic staining.
    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer EDTA pH 9.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.
