Background
Basement membrane components play an important role in cell adhesion, locomotion, differentiation and embryonic compartmentalization. Although the precise composition and structure of basal laminae varies from tissue to tissue, as well as within the same tissue at different developmental stages, most mature basal laminae contain type IV collagen, laminins, heparan sulphate proteoglycans and entactin (or niDogen). Entactin is a sulphated glycoprotein of approximately 150 kD.

Source
ELM1 is a rat monoclonal IgG2a antibody derived by fusion of X63 Ag 8.653 mouse myeloma cells with spleen cells from a Fisher rat immunized with a partially purified preparation of laminin from the EHS mouse tumor.

Product
Each vial contains 100 ul 1 mg/ml purified monoclonal antibody in PBS containing 0.09% sodium azide.

Specificity
ELM1 reacts with entactin.

Applications
ELM1 is suitable for immunoblotting, immunocytochemistry and immunohistochemistry on frozen tissues. Optimal antibody dilution should be determined by titration; recommended range is 1:25 – 1:200 for immunohistochemistry with avidin-biotinylated Horseradish peroxidase complex (ABC) as detection reagent, and 1:100 – 1:1000 for immunoblotting applications.

Storage
The antibody may be stored at +4°C. For prolonged storage prepare appropriate aliquots and store at or below -20°C. Prior to use, an aliquot is thawed slowly in the dark at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance or the concentration of the product.

Shipping Conditions: Ship at ambient temperature.
