Stability of ovine serum protein fractions under different storage conditions

Rock Stability under Different Fluid Flow Conditions

Stability of carotenoid diets during feed processing and under different storage conditions.

The stability of formulated carotenoid diets during feed processing and under different storage conditions were studied. All carotenoid diets were split into two groups with one group containing BHT (acting as an antioxidant) at 250 ppm and the other without BHT. The experiment was divided into two parts. First, all diets were evaluated in total carotenoid (TC) loss during feed processing, in d...

Stability of prothrombin time and activated partial thromboplastin time tests under different storage conditions.

Prothrombin time (PT) and activated partial thromboplastin time (aPTT) are common laboratory tests that are useful in the diagnosis of coagulation disorders and monitoring anticoagulant therapy. Recent expansions in the outreach laboratory services at our institution prompted us to investigate the shipping limitations for some tests, including PT and aPTT. Although we followed NCCLS guidelines ...

Evaluation of glucose-6-phosphate dehydrogenase stability in blood samples under different collection and storage conditions.

To the Editor: Fujimoto et al. (1 ) reported that the stability of galactose 1-phosphate in dried blood spots for neonatal screening was adversely affected by humidity and temperature, especially when low-value samples are evaluated. We extend these findings to glucose-6-phosphate dehydrogenase (G-6-PD; EC 1.1.1.49) activity, deficiency of which is by far the most common genetic disease worldwi...

Stability of plasma electrolytes in Barricor and PST II tubes under different storage conditions

INTRODUCTION Sample stability can be influenced by many different factors; evaporation and leakage from residual cells are the most relevant factors for electrolytes. During the analytical phase, samples are usually kept uncapped at room temperature. Once samples are processed, they are usually stored sealed and refrigerated. Long turnaround time and the possibility of "add-on test" need consid...
