| amphotropic packaging cell lines | <cell culture, molecular biology> Clonal entities that express genes or act as viral vectors that infect cell lines to stably infect and then express genes of choice. Usually an amphotropic virus. (04 Nov 1997) |
|---|---|
| packaging | <molecular biology, virology> Of a virus, the process by which the genetic material is encapsulated by the coat proteins. (18 Nov 1997) |
| product packaging | Form in which product is processed or wrapped and labelled. (12 Dec 1998) |
| drug packaging | Containers, packaging, and packaging materials for drugs and biological products. These include those in ampule, capsule, tablet, solution or other forms. Packaging includes immediate-containers, secondary-containers, and cartons. In the united states, such packaging is controlled under the federal food, drug, and cosmetic act which also stipulates requirements for tamper-resistance and child-resistance. Similar laws govern use elsewhere. drug labeling is also available. (12 Dec 1998) |
| food packaging | Containers, packaging, and packaging materials for processed and raw foods and beverages. It includes packaging intended to be used for storage and also used for preparation of foods such as microwave food containers versus cooking and eating utensils. Packaging materials may be intended for food contact or designated non-contact, for example, shipping containers. Food labeling is also available. (12 Dec 1998) |
| alu sequence | Any of a family of short (300 basepairs long) repeated sequences that occur throughout the human genome. (09 Oct 1997) |
| amino acid sequence | The sequence of amino acids as arrayed in chains, sheets, etc., within the protein molecule. This is referred to as the primary structure of proteins. It is of fundamental importance in determining protein conformation. (12 Dec 1998) |
| autonomously replicating sequence | <molecular biology> This is a chromosomal sequence that allows plasmids to replicate on their own in yeast. (02 Jan 1998) |
| base sequence | <molecular biology> The order of nucleotide bases in a DNA molecule. (09 Oct 1997) |
| base sequence analysis | <molecular biology> A method, sometimes automated, for determining the base sequence. (09 Oct 1997) |
| canonical sequence | Of a series of related DNA, RNA or protein sequences, the sequence that reflects the most common choice of base or amino acid at each position. Areas of particularly good agreement often represent conserved functional domains. The generation of consensus sequences has been subjected to intensive mathematical analysis. (18 Nov 1997) |
| carbohydrate sequence | The sequence of carbohydrates within polysaccharides, glycoproteins, and glycolipids. (12 Dec 1998) |
| palindromic sequence | <molecular biology> Nucleic acid sequence that is identical to its complementary strand when each is read in the correct direction (e.g. TGGCCA). Palindromic sequences are often the recognition sites for restriction enzymes. Degenerate palindromes with internal mismatching can lead to loops or hairpins being formed (as in tRNA). (18 Nov 1997) |
| recognition sequence | A nucleotide sequence --typically composed of 4, 6, or 8nucleotides -- that is recognised by a restriction endonuclease. Type II enzymes cut (and theircorresponding modification enzymes methylate) within or very near the recognition sequence. (09 Oct 1997) |
| regulatory sequence | <molecular biology> DNA sequence to which regulatory molecules such as promotors or enhancers bind, thereby altering the expression of the adjacent gene. (18 Nov 1997) |
