We did a retrospective analysis of age and sex and identified a very accurate relationship between test results and age. From 50 to 85 years, in both sexes, an increase in positive results was observed, amounting to three times as many as those in younger patients. Considering this result, ...
N Latex FLC kappa and lambda assays: Use built-in pre-reaction protocols for detection of antigen excess. Provide more-consistent results. Generate fewer false-low test results, even in samples with very high FLC concentrations. Reduce the need for costly reruns. Nephelometry has been ...
In addition, cytophilic antibody did not obscure results in normal controls. Monoclonality was detected in 106 patient specimens, with 89 showing gross involvement with a predominant monoclonal B-cell process. However, in 43% of the grossly monoclonal specimens, there was failure to detect mono...

As there is no upper limit, the lateral flow strip will continue to show positive results at concentrations greater than 20 µg/mL, visualized by complete loss of test lines (test lines closest to the sample will disappear first). It is not recommended to use at concentrations less than ...
The gene rearrangement process that generates the immunoglobulin molecule results in either a productive kappa gene or a productive lambda gene. The mechanics of the rearrangement process normally produce approximately twice as many kappa-bearing cells as lambda bearing.28 This ratio is maintained in ...
Reliable and high analytical performance results with correct estimation of FLC values without antigen excess or overestimation by polymerization vs Nephelometry / Turbidimetry Methods. Trust in the results with concordance value between SPE and FLC Kappa & FLC Lambda which help on interpretation results...
We first described the recurrence of CD5 positive MALT lymphoma in the oral cavity and compared the immunohistochemical expressions of CD5, lambda, and kappa between the primary and recurrent tumors.Background Mucosa-associated lymphoid tissue (MALT) lymphoma is a type of extranodal marginal zone B...
Results Data are shown in Table1(N. of included patients: 373). Table 1 Absolute concentrations of kappa (K) and lambda (L) free light chains (FLC), CSF ratios and indexes were determined in multiple sclerosis (MS), inflammatory neurological diseases other than MS (ID), and non-ID. ...
Noteworthy, the kappa-RBD formulated vaccine with CpG and alum induced pseudovirus neutralizing antibody titers against SARS-CoV-2 kappa, delta, lambda, beta, and omicron variants as well as the WT virus. These results indicate that the designed vaccine has broad-spectrum activity and the ...
