Rabbit Anti-Toso, CT (Regulator of Fas-induced Apoptosis, Fas Apoptotic Inhibitory Molecule 3, FAIM3) (MaxLight 650)

MaxLight™650 is a new Far-IR stable dye conjugate comparable to Alexa Fluor™647, DyLight™649, Cy5™ and offers better labeling efficiency, brighter imaging and increased immunodetection. Absorbance (655nm); Emission (676nm); Extinction Coefficient 250,000.

Toso, also known as Fas Apoptotic Inhibitory Molecule 3 (FAIM3). Toso is expressed by lymphoid and hematopoietic cells and is up-regulated by T-cell activation. Toso expressing cells have increased resistance to Fas-, FADD-, and TNFalpha-induced apoptosis. Toso is membrane bound, and is thought to directly bind to FADD, disrupting DISC formation and thus inhibiting caspase-8 activation. Toso is a potential proto-oncogene, and could be a therapeutic target for use in the treatment of autoimmune diseases. Despite its predicted molecular weight, Toso often migrates at 60kD in SDS PAGE.
Applications
Suitable for use in Western Blot. Other applications not tested.
Recommended Dilution
Western Blot: 1-2ug/ml detects a band of ~43kD in human lung tissue lysate. Optimal dilutions to be determined by the researcher.
Storage and Stability
Store product at 4°C in the dark. DO NOT FREEZE! Stable at 4°C for 12 months after receipt as an undiluted liquid. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: MaxLight™650 conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial prior to removing the cap.
Note: Applications are based on unconjugated antibody.
Immunogen
A 13aa peptide from near the carboxy terminus of human Toso.
Form
Supplied as a liquid in PBS, pH 7.2. Labeled with MaxLight™650.
Purity
Purified by immunoaffinity chromatography.
Specificity
Recognizes an epitope within the C-terminal region of human Toso. Species sequence homology: mouse, rat.

Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
