Abstract: The invention deals with a method of quantitative determination of sarcosine in a biological sample with a sensitivity from 0.05 ?M to 1.00 ?M by means of anti-sarcosine antibodies and peroxidase-active gold nanoparticles or quantum dots, applying the ELISA and LFIA methods. It is based on the usage of immunised antibodies that specifically distinguish sarcosine. The subject matter of the invention is also a diagnostic strip for the determination by means of the LFIA method, which is designed for qualitative and quantitative determination of sarcosine in a biological sample. It is convenient for a routine determination of sarcosine in diagnostic laboratories, which may be performed within 2-3 hours, utilising equipment commonly available in such laboratories, and it may be also used for self-diagnostics.

Abstract: The present invention relates to a diagnostic strip for an enzymatic test for determining the amount of sarcosine and creatinine based on the formed hydrogen peroxide in a biological sample or in an environmental sample with visual or electronic evaluation of intensity of the colour product. The diagnostic strip consists of a pad to which zones of an absorbent matrix are applied to conduct the test, consisting of sample zone (V) at one end of the strip followed by one or two reaction zones (R1), (R2), where to (R1) zone is applied reagent containing sodium salt of 3-(N-ethyl-3-methylaniline) propanesulfonic acid and to (R2) zone is applied reagent containing peroxidase and 4-amino-2,3-dimethyl-1-phenyl-3-pyrazole. Reaction zones are followed by detection zone (D) and beeswax zone (Z), forming the other end of diagnostic strip.

Abstract: Rotary wrenching tools are sized, in one embodiment, to strongly and adequately receive heads of fastening members of two or more nominal sizes having maximum size ratios in the approximate size ranges of 1.0053-1.1430 for square heads and 1.0053-1.0600 for hexagonal heads. Visible indicia of the sizes of at least two different fastener head sizes are carried adjacent each opening.
