50 µg specific antibody, lyophilized. Affinity purified with the immunogen. Albumin was added for stabilization. For reconstitution add 50 µl H2O to get a 1mg/ml solution in PBS. Then aliquot and store at -20°C to -80°C until use. Antibodies should be stored at +4°C when still lyophilized. Do not freeze! |

| Immunogen | Synthetic peptide corresponding to AA 33 to 38 from human Abeta38 (UniProt Id: P05067) |
| Reactivity |
Reacts with: human (P05067), rat (P08592), mouse (P12023). Other species not tested yet. |
| Specificity | Specific for Abeta 38. |
| Remarks |
WB: Detects purified Abeta 38. Complex samples like brain extracts still have to be tested. Boil membrane after blotting for 3min. |

Amyloid deposits, also called plaques, of Alzheimer's patients consist of several protein components like the amyloid beta-peptides (Abeta, Aβ) 1-40/42/43 and additional C- and N-terminally modified fragments of Abeta as for instance Abeta pE3 and Abeta pE11.
An additional Abeta variant, Abeta38, is more soluble compared to other Abeta species and is not found in plaques of sporadic Alzheimer´s cases. However, it is detected in the blood-vessel walls of a subset of patients with severe cerebral amyloid angiopathy. It especially accumulates in brains of patients carrying mutations in the Abeta coding region.
Cleavage of amyloid precursor protein APP by β- and γ- secretases results in the generation of the Aβ (βA4)peptide, whereas α-secretase cleaves within the Aβ sequence and prevents the formation of Abeta from APP.
