WebAug 6, 2013 · Spectratyping generates data about T-cell receptor CDR3 length distribution for each BV gene but is technically complex. Flow cytometry can also be used to generate data about T-cell receptor BV gene usage, but its utility has not been compared to or tested in combination with spectratyping. WebTCR Vβ18 Antibodies. TCR Vβ18 is also called TCRBV18S1. Vβ18 is a single member subfamily (PH29 sequence identical to the HBVT56 sequence). It is expressed by 0.7% to 1.4% of peripheral CD3+ cells in normal blood. This sequence is also referred to as TRBV18 (based on the IMGT gene nomenclature). WebAug 1, 2003 · Nevertheless, these approaches only provide an indirect measurement of TCR diversity. Recently, the use of spectratyping has emerged as a useful laboratory technique to measure TCRs [390]. In this approach, the lengths of different CDR3 (a portion of the recombinant TCR) are used to calculate the number of T-cell clonotypes [379]. christina e. tolley md
