test Q#4 I may have copied down wrong :analytical error indicates what when it goes in which direction
systemic error influences observations constantly in one direction (higher or lower) , by measuring slope and y intercept you can estimate systemic error
RANDOM ANALYTICAL ERRRandom error: Error varies from sample to sample.Causes include instrument instability, temperature variations, reagent variation, handling techniques, and operator variables.. Random error is present in all measurements and can be either positive or negative.Random error is calculated as the SD of the points about the regression line (Sy/x). Sy/x
essentially refers to average distance of the data from the regression line (Fig. 4-7). The higher the Sy/x, the wider is the scatter and

Define EIA enzyme immunoassay uses enzyme bound antibody to detect angtigen, substrate produces colorogenic reaction
Why is chemiluminescence better The detection limits are very small , up to 1 zmol and its specificity is the alkaline phosphatase is the most sensitive chemiluminescent assay
Why are EMIT assays different? Think preparation, don’t have to separate first, skip a whole step.Its unique feature is the ability to detect this binding without resorting to a cumbersome separation of the bound component. This is accomplished by including in the mixture of antibodies and sample an enzyme that is attached to the drug. Antibodies that do not become bound to drug in the sample bind instead to this enzyme-drug "conjugate". The conjugate is designed in such a way that when antibodies bind to its drug portion, the enzyme is deactivated. The more drug there is in the sample, the more of the antibody is bound to it and less is available to deactivate the conjugate. If an enzyme substrate is present that is converted to a colored or fluorescent product, the presence of drug will inhibit the formation of the detectible product to a degree related to the concentration of the drug.
Define southern blot western and northernSouthern DNA extracted from sample, enzymatically digested, separation by
electrophoresis, denatured, transferred to a membrane, and finally probed to produce a band.
Northern same as southern but RNA instead of DNAWestern protein separationELISA direct and indirect tesing for antigen or antibody. Specificity confirmed with Western blot protein separation technique to isolate specific protein you are looking for
Western blot technique used to detect antibodies to specific epitopes of electrophoretically separated substrates of antigens. A technique where electrophoresis of antigenic material yields separation of the antigenic components by molecular weight. Blotting the separated antigen to nitrocellulose retains the electrophoretic position and will have a reaction with specific antibodies, if present, in the different antigenic bands. EIA reactions then detects the antibodies that have been bound to the antigens on the nitrocellulose membrane, the EIA reaction characterizes the antibody specificity. This is done to confirm specificity of antibodies detected by ELISA
EMIT capture method . detects very small concentrations of antigen with multiple epitopes, no separation step
Common polymorphisms seen in genes SNP single nucleiotide polymorphisms

Competitive immunoassay. The labeled Ag(*) aka ‘tracer’ competes with the same unlabeled Ag to bind to a limited number of binding sites. This is done with known and constant amt of Ab binding sites and Ag* to determine unknown amount of Ag that isn’t labeled. More flouresence = more Ag* to Ag ratio. Low fluorescence= more Ag to Ag* ratio

Osmotic force— plasma proteins function in the distribution of water throughout the compartments of the body. Their colloid osmotic force, due to their size, does not allow protein to cross the capillary membranes. As a result, water is absorbed from the tissue into the venous portion of the capillary. When the concentration of plasma proteins is significantly decreased, the concomitant decrease in the plasma colloidal osmotic (oncotic) pressure results in increased levels of interstitial fluid and edema. This is often seen in renal disease when proteinuria results in a decreased plasma protein concentration and swelling of the hands and feet.

Define reactant order kineticsFirst order kinetics where the reaction rate is directly proportional to the substrate concentration. Substrate binds readily to free enzyme at a low substrate concentration. If the amount of enzyme exceeds the amount of substrate, the reaction rate steadily increases as more substrate is added. Maximum reaction velocity is reached when the substrate concentration is high enough to saturate all available enzyme.Zero order kinetics where the reaction rate depends on the enzyme concentration. Where after product is formed the resulting free enzyme immidiatly combines with excess free substrate

Primary The primary structure refers to amino acid linear sequence of the polypeptide chain. The primary structure is held together by covalent or peptide bonds
Secondary Two main types of secondary structure, the alpha helix and the beta strand or beta sheets, These secondary structures are defined by patterns of hydrogen bonds between the main-chain peptide groups.
Tertiary structure Tertiary structure refers to three-dimensional structure of a single protein molecule. The alpha-helices and beta-sheets are folded into a compact globule. non-specific hydrophobic interactions lock into place specific tertiary interactions, such as salt bridges, hydrogen bonds, and the tight packing of side chains and disulfide bonds.
