Application Notes
WB: Use at an assay dependent dilution.
Species
Human
Recommend Usage
1. Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube.2. Re-dissolve the pellet using 200uL pure water and boil for 2-5 min.
Sequence Construction
A DNA sequence encoding the human cathepsin A isoform b (Met 1-Tyr 480) (NP_001121167.1) was expressed with a N-terminal signal peptide and a C-terminal polyhistidine tag.
Preparation Method
Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors. Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
Preparation and Storage
Store at 4 degree C for up to twelve months from date of receipt. After re-dissolution, aliquot and store at -80 degree C for up to twelve months. Avoid repeated freeze-thaw cycles.
Samples are stable for up to twelve months from date of receipt.
Related Product Information for CTSA cell lysate
Lysosomal carboxypeptidase, cathepsin A (protective protein, CathA), is a component of the lysosomal multienzyme complex along with beta-galactosidase (GAL) and sialidase Neu1, where it activates Neu1 and protects GAL and Neu1 against the rapid proteolytic degradation. Cathepsin A is a multicatalytic enzyme with deamidase and esterase in addition to carboxypeptidase activities. It was recently identified in human platelets as deamidase. In vitro, it hydrolyzes a variety of bioactive peptide hormones including tachykinins, suggesting that extralysosomal cathepsin A plays a role in regulation of bioactive peptide functions. It is a member of the alpha/beta hydrolase fold family and has been suggested to share a common ancestral relationship with other alpha/beta hydrolase fold enzymes, such as cholinesterases. Cathepsin A defects are linked to multiple forms of Galactosialidosis with a combined secondary deficiency of beta-galactosidase and neuraminidase. Cathepsin A is a key molecule in the onset of galactosialidosis and also highlight the therapeutic acts in vivo as an endothelin-1-inactivating enzyme and strongly confirm a crucial role of this enzyme in effective elastic fiber formation.

This Human Cathepsin A overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of Cathepsin A protein from the overexpression lysate was verified.

Uniprot Description

CTSA: Protective protein appears to be essential for both the activity of beta-galactosidase and neuraminidase, it associates with these enzymes and exerts a protective function necessary for their stability and activity. This protein is also a carboxypeptidase and can deamidate tachykinins. Defects in CTSA are the cause of galactosialidosis (GSL). A lysosomal storage disease associated with a combined deficiency of beta-galactosidase and neuraminidase, secondary to a defect in cathepsin A. All patients have clinical manifestations typical of a lysosomal disorder, such as coarse facies, cherry red spots, vertebral changes, foam cells in the bone marrow, and vacuolated lymphocytes. Three phenotypic subtypes are recognized. The early infantile form is associated with fetal hydrops, edema, ascites, visceromegaly, skeletal dysplasia, and early death. The late infantile type is characterized by hepatosplenomegaly, growth retardation, cardiac involvement, and a normal or mildly affected mental state. The juvenile/adult form is characterized by myoclonus, ataxia, angiokeratoma, mental retardation, neurologic deterioration, absence of visceromegaly, and long survival. Belongs to the peptidase S10 family.

Product Notes

The CTSA ctsa (Catalog #AAA8113895) is a Cell Lysate produced from HEK293 Cells and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is 463aa. AAA Biotech's Cathepsin A can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB). WB: Use at an assay dependent dilution. Researchers should empirically determine the suitability of the CTSA ctsa for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. The amino acid sequence is listed below: Met1-Tyr48 0. It is sometimes possible for the material contained within the vial of "Cathepsin A, Cell Lysate" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
