Abstract:
Recombinant nucleic acid molecules are described. The molecules have a first sequence encoding a Hepatitis B virus core antigen and a second sequence encoding at least one T cell epitope inserted within the first sequence. Vectors and compositions containing these molecules are also described. Methods of eliciting an immune response using these molecules are also described.
Abstract:
A method for producing antibodies and plant protein toxins in plant cells is described which includes the steps of providing a genetic construct to encode the secretable protein, delivering copies of the construct into a liquid suspension culture of tobacco cells, selecting for cells that have acquired the genetic construct, and allowing the desired protein to accumulate in the liquid media in which the plant cells are grown, and isolating the desired protein away from the tobacco cells.
Abstract:
Reagents useful in nucleic acid immunization techniques are described. More particularly, adjuvanted genetic vaccine compositions are described, as are methods of using those compositions for inducing an enhanced immune response against a selected antigen.

A method for producing antibodies in plant cells including the steps of providing a genetic construct that encodes a secretable mammalian single chain antibody, delivering copies of the construct into a liquid suspension culture of tobacco cells, selecting for cells that have acquired the genetic construct, allowing the antibody to accumulate in the liquid to a concentration over 25 mg/l and isolating the antibody away from the tobacco cells.

Abstract:
There is disclosed herein a spring battery retainer that is used to secure a small "coin" or "button" battery to a printed circuit (PC) card or the like. Use of the spring battery retainer provides for positive location of the battery, inexpensive electrical contacts for the battery terminals and positive spring compression that is necessary to insure hard contact with the cathode and the anode terminals of the battery. The battery is easily installed and removed by slightly lifting one end of the battery retainer and sliding the battery in or out. A bend in the spring battery retainer provides sufficient hold-down pressure so that the battery makes reliable contact with an electrical pad located on a PC board. The spring battery retainer is inserted into the PC card and then soldered to it in much the same way as a standard electrical component such as a resistor. The dimensions of the spring battery retainer can be varied so that coin or button batteries of various sizes can be securely fastened to a PC card.
