Technical Data
C5819-50A
CLAC-P, NC2-2 Region (Collagen-like Alzheimer Amyloid Plaque Component)
Description:
Antibodies against senile plaque (SP) amyloid obtained a clone 9D2, which labeled amyloid fibrils in SPs and reacted with approximately 50/100kD polypeptides in Alzheimer's disease (AD) brains. The 9D2 antigen was identified as CLAC (collagen-like Alzheimer amyloid plaque component), and its precursor as CLAC-P/collagen type XXV. Both secreted and membrane-tethered forms of CLAC-P/collagen type XXV specifically bound to fibrillized Abeta, implicating these proteins in beta-amyloidogenesis and neuronal degeneration in AD.

Applications:
Suitable for use in Western Blot. Other applications not tested.

Recommended Dilution:
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

A synthetic peptide mapping to residues 155-169 [KGEQGDQGPRMVFPK] of the NC2-2 region of human and mouse CLAC-P.
Purity:
Purified by immunoaffinity chromatography.
Form
As reported
Specificity:
Reacts with residues 155-169 [KGEQGDQGPRMVFPK] of the NC2-2 region of human and mouse CLAC-P. Detects bands of 50, 70 and 100kD in SPs of AD brain, but not in diffuse plaques of non-demented aged individuals, diffuse deposits in sub-cortical structures and cerebellum in AD nor in cerebral amyloid angiopathy. Species Crossreactivity: Human and mouse. Other species have not been tested.
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
