| Specificity / Sensitivity | Calpastatin Antibody detects endogenous levels of total calpastatin protein. |
| Source / Purification | Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to human calpastatin. Antibodies are purified by peptide affinity chromatography. Western Blotting
Western blot analysis of extracts from A20 and MDA-MB-231 cells using Calpastatin Antibody. |
| Background | Calpain is a thiol proteinase that is functionally active as a heterodimer composed of a small regulatory subunit and one of at least two large catalytic subunits (calpain 1 or calpain 2). In vitro , calpain 1 (mu-calpain) requires micromolar levels of calcium, while calpain 2 (M-calpain) requires millimolar levels of calcium for activation (1). Calpastatin negatively regulates autoproteolytic cleavage of calpain 1 between Gly27 and Leu28 in a calcium dependent manner (2). In particular, calpastatin binds and inhibits calpain when calcium levels are high and is released when calcium levels go down. Calpastatin contains five domains, a unique N-terminal domain L with no inhibitory effects and four homologous domains (CAST 1-4) that can inhibit heterodimeric calpain 1 and 2 (3). |

文献和实验Preparation of Calpastatin Samples for Western Blotting
Determination of calpastatin levels in cells or tissues by Western blotting using antibodies, or by assay of calpain inhibitory activities in vitro, may be required to assess the role and the level of calpastatin, with respect to the levels
Purification of Recombinant Calpastatin Expressed in Escherichia coli
Calpastatin is an endogenous inhibitor protein specific for calpain (1 ,2 ). Other calpain-inhibiting reagents such as EDTA, E-64, leupeptin, and calpain inhibitor I (N -acetyl-L-leucyl-L-leucyl-L-norleucinal), are frequently used
Purification of - and m-Calpain and Calpastatin from Animal Tissues
This chapter describes procedures for purification of μ-calpain, m-calpain, and calpastatin simultaneously from a single tissue sample. The procedures and reagents described apply equally well to purification
