Monoclonal mouse anti-neuron specific enolase

CAT#: RDI-TRK4N6-5G10, or   RDI-TRK4N6-5E2,or

           RDI-TRK4N6-5A4,   or   RDI-TRK4N6-1C1

PRICE: $375.00/mg or   $344.00/mg   2 or more (any combination) Bulk on request

Clone: 5G10, 5E2, 5A4, 1C1

These clones have been derived from hybridization of SP2/0 myeloma cells with spleen cells of a Balb/c mice immunized with purified neuron-specific enolase from human brain.

Specificity: Neuron-specific enolase (NSE), human

Reactivity: MoAb react with 45 kD band corresponding to NSE in immunoblotting of human brain extracts

Specific antibody titer in indirect ELISA is 1/1, 000.000 for all clones. MoAb 5G10, 5A4 and 5E2 may be used for immunohistochemistry on formalin-fixed and paraffin-embedded sections (recommend clone 5G10). Recommended dilution is 1:100=1:300. Optimal dilution must be determined by experimentation.

All antibodies work in ELISA.

The following pairs of our anti-NSE clones can be used to make an ELISA: 1C1 - 5A4, 1C1 - 5E2 and   1C1 - 5G10. According our data best results were   obtained with MAb 5G10 direct coating and MAb   1C1-HRP conjugate. Sensitivity approx 2-5ng/ml

(clone 1C1 can be purchased HRP conjugated, cat#RDI-TRK4N6-1CHRP  $688.00/1mg, $625.00/mg 2+)

Mouse isotype: Clones 5E2, 1C1, 5A4 - IgG2a

                        clone 5G10 - IgG2b

Application: Detection of NSE in ELISA and immunohistochemistry.

Presentation:Each vial contains 1 ml of antibodies with concentration 1 mg/ml, in PBS, pH 7.4, containing 0.1% of sodium azide as preservative. Store 4-8 DEG C.

Material safety note: This product is sold as an antibody preparation for research purpose only. Standard Laboratory Practices should be followed when handling this material. Contains sodium azide (0.1%) as preservative. Although the amount of sodium azide is very small appropriate care must be taken when handling this product.
