Préparation de l'échantillon:

Sample Handling
All blood components and biological materials should be handled as potentially hazardous. Follow universal precautions when handling and disposing of infectious agents.
100 µl of diluted sample is required per well.
Samples must be assayed in duplicate each time the assay is performed.
Samples should be frozen if not analyzed shortly after harvest. For long-term storage, aliquot and freeze samples. Avoid repeated freeze-thaw cycles when storing samples.
If particulate is present in samples, centrifuge prior to analysis.
If the integrity of the sample is of concern, make a note on the Plate Template and interpret results with caution.

Sample Dilution
Samples must first be diluted prior to testing.
Suggested starting dilutions for samples:
- For cell and tissue lysates, dilute samples 1:4 in Standard and Sample Diluent.
For example, dilute 35 µL of sample in 105 µL Standard and Sample Diluent. Mix well.
Note: If values for samples are not within the range of the standard curve, optimal sample dilutions need to be determined.

Prepare at least 125 µL of sample in Standard and Sample Diluent. Mix samples well prior to analysis.
Note: Plasma samples are not recommended.

Calcul des résultats:

Duplicate absorbance values should be within 10% of each other. Care should be taken when interpreting data with differences in absorbance values greater than 10%.

1. Prepare a standard curve to determine the amount of Hsp70 in an unknown sample. Plot the average absorbance obtained for each standard concentration on the vertical (Y) axis versus the corresponding Hsp70 concentration on the horizontal (X) axis using graph paper or curve-fitting software.

2. Calculate the Hsp70 concentration in unknown samples using the prepared standard curve. Determine the amount of Hsp70 in each unknown sample by noting the Hsp70 concentration (X axis) that correlates with the absorbance value (Y axis) obtained for the unknown sample.

3. Multiply the Hsp70 concentration obtained by the dilution factor to determine the amount of Hsp70 in the undiluted sample.

Sujet: HSP70 genes encode abundant heat-inducible 70- kDa HSPs (HSP70s). In most eukaryotes HSP70 genes exist as part of a multigene family. They are found in most cellular compartments of eukaryotes including nuclei, mitochondria, chloroplasts, the endoplasmic reticulum and the cytosol, as well as in bacteria. The genes show a high degree of conservation, having at least 5O% identity. The N-terminal two thirds of HSP70s are more conserved than the C-terminal third. HSP70 binds ATP with high affinity and possesses a weak ATPase activity which can be stimulated by binding to unfolded proteins and synthetic peptides. When HSC70 (constitutively expressed) present in mammalian cells was truncated, ATP binding activity was found to reside in an N-terminal fragment of 44 kDa which lacked peptide binding capacity. Polypeptide binding ability therefore resided within the C-terminal half. The structure of this ATP binding domain displays multiple features of nucleotide binding proteins. All HSP70s, regardless of location, bind proteins, particularly unfolded ones. The molecular chaperones of the HSP70 family recognize and bind to nascent polypeptide chains as well as partially folded intermediates of proteins preventing their aggregation and misfolding. The binding of ATP triggers a critical conformational change leading to the release of the bound substrate protein. The universal ability of HSP70s to undergo cycles of binding to and release from hydrophobic stretches of partially unfolded proteins determines their role in a great variety of vital intracellular functions such as protein synthesis, protein folding and oligomerization and protein transport.
