Specificity
ab28257 recognizes the amino terminal end of the large subunit of Calpain 1. The antibody does not recognize amino-processed Calpain 1, and can be used to discriminate between latent and amino-processed forms. Also, it does not cross react with the other calpain family members (M Calpain, Calpain 94, ncl2, ncl3, etc.). -

Applications
The Abpromise guarantee
Our Abpromise guarantee covers the use of ab28257 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) |
1/1000 - 1/5000. Detects a band of approximately 82 kDa (predicted molecular weight: 82 kDa). 1/1000, when using colorimetric substrates such as BCIP/NBT - 1/5000, when using chemiluminescent substrates. But note that when used against the reduced protein, ab28257 identifies bands at 80 kDa, 68 kDa, and a series of further cleaved forms. Dilution optimised using Chromogenic detection.
|
ICC/IF |
Use a concentration of 1 - 5 µg/ml.

Images

ICC/IF image of ab28257 stained MCF7 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab28257, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
