Abstract

The present disclosure provides systems, kits and methods for determining the copy number of a mouse TCR transgene. The primers are specific to the conserved regions of the mouse TCR gene. The primers/probes provide good amplification efficiency and can quickly and accurately determine the copy number of a mouse TCR transgene.

Claims (17)

1 . A system for determining a copy number of a mouse T cell receptor (TCR) gene, the system comprising

(i) a forward primer comprising the nucleic acid sequence set forth in SEQ ID NO:1 and (ii) a reverse primer comprising the nucleic acid sequence set forth in SEQ ID NO:2, and (iii) a probe comprising a detectable label.

2 . The system of claim 1 , wherein the detectable label is a fluorescent label.

3 . The system of claim 1 , wherein the probe comprises the nucleic acid sequence set forth in SEQ ID NO: 3.

4 . The system of claim 2 , wherein the fluorescent label comprises a fluorescent reporter and a fluorescent quencher.

5 . The system of claim 4 , wherein the fluorescent reporter is at a 5′ end of the probe, and wherein the fluorescent quencher is at a 3′ end of the probe.

6 . The system of claim 4 , wherein the fluorescent reporter is at a 3′ end of the probe, and wherein the fluorescent quencher is at a 5′ end of the probe.

7 . A method for determining a copy number of a mouse T cell receptor (TCR) gene in a sample, the method comprising:

(a) contacting the sample with the system of claim 1 ; and

(b) conducting a nucleic acid amplification reaction.

8 . A kit for determining a copy number of a mouse T cell receptor (TCR) gene, the kit comprising:

(i) a forward primer comprising a nucleic acid sequence set forth in SEQ ID NO:1 and (ii) a reverse primer comprising a nucleic acid sequence set forth in SEQ ID NO:2, and (iii) a probe comprising a detectable label.

9 . The kit of claim 8 , wherein the detectable label is a fluorescent label.

10 . The kit of claim 8 , wherein the probe comprises the nucleic acid sequence set forth in SEQ ID NO: 3.

11 . The kit of claim 9 , wherein the fluorescent label comprises a fluorescent reporter and a fluorescent quencher.

12 . The method of claim 7 , wherein the mouse TCR gene is a transgene.

13 . The method of 9 , wherein the nucleic acid amplification reaction is polymerase chain reaction (PCR).
