Optimized DNA sequence encoding Human Carnosinase -CNDP1 (SER28 - HIS508) mature chain including a C-terminal His tag was expressed in HEK293 cells.
Recombinant Human Carnosinase (CN1) is a protein consisting of 488 amino acid residue subunits,due to glycosylation migrates as an approximately as 69kDa band protein on reduced SDS-PAGE.
>95%, as determined by SDS-PAGE and HPLC
The activity was measured by the ability to cleave carnosine, the activity was calculated to be >250 pmol/min/Ág
Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
Recombinant human Carnosinase (CNDP1) is lyophilized from 0.2 μm filtered PBS solution, pH7.2 , 5% Trehalose.
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Recombinant Human Carnosinase (CNDP1)can be stored in working aliquots at 2° - 8° C for one month, or at -20°C to -70°C for twelve months.
Avoid repeated freeze/thaw cycles.

Serum carnosinase, a
dipeptidase belonging to the
M20 metalloprotease family,
is the rate-limiting enzyme
for the hydrolysis of
carnosine into β-alanine and
histidine. Carnosine is an
nonenzymatic glycosylation ,
prevents high glucoseľ
induced extracellular matrix
accumulation, and prevents
cross-linking of proteins
caused by reactive aldehydes
