International Classification:

C07H 21/04
C12N 15/64
US Classification:

435 914, 4353201, 536 242
Abstract:

Vector preparations and cloning constructs suitable for use in cloning are provided. Vector preparations are double-stranded DNA molecules having two 3′ termini, each terminus having a single base pair overhang that is capable of hybridizing to a single base pair overhang on a double stranded polynucleotide sequence to be cloned. The overhang of the vector preparation is suitably a dCMP and the overhang of the polynucleotide sequence to be cloned is suitably a dGMP. In other embodiments, the overhang of the polynucleotide sequence to be cloned is any ddNTP and the corresponding overhang of the vector preparation is any base that pairs to the ddNTP. The latter embodiment is particularly suited to preparing recombinant molecules having only a single insert. Methods of cloning, methods of preparing libraries of recombinant molecules and kits for carrying out the methods are also provided.

US Patent:

20160348189, Dec 1, 2016
Filed:

May 27, 2016
Appl. No.:

15/166497
Inventors:

- Middleton WI, US
Thomas William Schoenfeld - Topsfield MA, US
Assignee:

LUCIGEN CORPORATION - Middleton WI
International Classification:

C12Q 1/70
C12Q 1/68
Abstract:

Methods of detecting RNA, such as ribosomal RNA (rRNA), messenger RNA (mRNA), and others. The methods include heating a cell comprising RNA in a solution to release the RNA from the cell, reverse transcribing the RNA into DNA with an enzyme, amplifying the DNA with the same enzyme, and detecting the amplified DNA. The heating, reverse-transcribing, and amplifying in at least some of the methods are performed at substantially the same temperature and a substantially constant temperature without adding additional reagents during or between the steps. The methods can be used to detect the presence of one cell type as distinguished from another cell type within a sample or to determine levels of gene expression, each without the need for elaborate extraction protocols.
