RDI Divison of Fitzgerald 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.

Storage: Store unopened lyophilized antibody at 4'C. Under these conditions, there is no significant loss in product performance up to the expiry date indicated on the vial label. The reconstituted antibody is stable for at least two months when stored at 4'C. For long term storage, it is recommended that aliquots of the antibody are frozen at -20'C (frost- free freezers are not recommended). Repeated freezing and thawing must be avoided. Prepare working dilutions on the day of use.

Acetycholine is a neurotransmitter which can control the neuritogenesis of hippocampal cells. The time at which receptors for acetylcholine are expressed may influence synaptogenesis and neuronal activity in developing hippocampus. In fully developed, adult hippocampus of mice, the expression of nicotinic acetylcholine-gated ion channel receptor alpha4 subunit is low. In embyronic mouse, expression is initially low, then rises to a maximum in only the second week of life and finally decreases to a minimum in adulthood. This transient expression profile of the alpha4 subunit suggests that nicotinic acetylcholine receptors may participate in the early postnatal maturation of hippocampal circuitry. Investigators of rat brain using immunohistochemistry for the alpha4 subunit indicates the staining of cell bodies and apical dendrite of pyramidal cells. This antibody may be useful for further studies of the functional role of nicotinic acetylcholine receptor alpha4 in the human brain during embryonic development , mayuration and lesion repair.
