(anti-Human and others as indicated)

RDI Divison of researchd Industries Intl  offers a wide line of  antibodies. Since no one antibody works best for all applications (neutralization, blotting, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.

Neurofilament NF-L Monoclonal Antibody

Catalog Number:   RDI-ALS24506     $344.00/100ul

Clone: DA2

Quantity: 100ul

Description: Neurofilaments are the 10nm or intermediate filament proteins found specifically in neurons, and are composed predominantly of three major proteins called NF-L, NF-M and NF-H. NF-L is the neurofilament light or low molecular weight polypeptide and runs on SDS-PAGE gels at about 68kDa. Antibodies to NF-L are useful for identifying neuronal cells and their processes in tissue sections and in tissue culture. NF-L antibody can also be useful in the diagnostics of neurofilament accumulations seen in many neurological diseases, such as Lou Gehrig's disease or Alzheimer's disease. Mutations in the protein coding region of the human NF-L gene appear to cause some forms of Charcot-Marie-Tooth disease (1).

Host Species: Mouse

Specificity: DA2 was raised against a preparation of enzymatically dephosphorylated pig neurofilaments including NF-L, NF-M and NF-H. Screening was by ELISA on the immungen followed by immunofluorescence microscopy. Clones which revealed strong staining were further characterized biochemically. It reacts with NF-L from human, cow, pig, mouse, rat and all other mammals, and also recognizes avian NF-L. It is strong and clean on western blots and works well on frozen sections, cells in tissue culture and on mildly formalin fixed histological sections.

Applications: For immunofluorescence, use DA2 diluted 1/100 to 1/500. For western blots use DA2 diluted 1/5,000 to 1:10,000.

Format: Sterile cell culture fluid plus sodium azide. DA2 is a IgG1 class antibody with a k light chain. Supplied at a concentration of 1mg/ml.

Storage: Maintain at +2-8°C for 3 months or at -20°C for longer periods. Stable for 1 year. Avoid repeated freeze-thaw cycles.
