Background of HSP27
Hsp27 is a chaperone of the sHsp (small heat shock protein) group among ubiquitin, alpha-crystallin, Hsp20 and others. The common functions of sHsps are chaperone activity, thermotolerance, inhibition of apoptosis, regulation of cell development, and cell differentiation. They also take part in signal transduction. The HSP27 gene has 3 exons. The mouse Hsp25 gene was mapped to chromosome 5 in a region homologous to 7q in the human. They also mapped the mouse Hsp105 gene to chromosome 5 but suggested that the human homolog is probably on 13q, not chromosome 7. The standard used in this kit is recombinant human HSP27, consisting of 205 amino acids with the molecular mass of 22.7kDa.

Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Human HSP27/HSPB1/Heat Shock Protein 27 ELISA Kit PicoKine® within the same batch/lot to ensure the consistency of the kits' performances. ELISA intra assay consistency is measured using wells from the same plate/assay kit. ELISA inter assay consistency is measured using wells from different plates from the same batch production/lot.

Question
Q: Are Boster Bio recombinant proteins and antibodies sterile?
Verified Customer
Verified customer
Asked: 2020-08-11
Answer
A: although the vials are bottled using aseptic techniques, heat-treated vials, and sterile stock solutions, they are not considered or guaranteed to be sterile. If sterile material is required for an experiment, the material can be filtered through a 0.2 micron filter designed for use with biological fluids.

Question
Q: how long can samples (cell cultures, serum, and plasma) be stored and still be stable for analysis HSP27 using the EK0881 Human HSP27 Picokine® ELISA Kit?
S. Evans
Verified customer
Asked: 2020-07-09
Answer
A: Boster Bio does not evaluate sample stability. Variations in sample collection, processing, and storage may change the stabilityof samples. It is recommend to assay sample on priority basis collection when possible, or aliquot into single use volumes and store samples frozen. avoid repetitive freeze-thaw cycles with the stored samples to prevent protein degradation.

Question
Q: Can HSP27 ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
Verified Customer
Verified customer
Asked: 2020-02-20
Answer
A: Unfortunately, Boster Bio has not routinely validated tissue homogenates as a sample type for ELISA kits. This does not mean that ELISA kits are not valid for other sample types than we have tested: it means further investigation is required. One will need to perform a spike and recovery study to determine if an unvalidated sample type will work with a particular kit. To perform a spike and recovery experiment, one should divide a sample into two aliquots. In one of the aliquots, the user should spike in a known amount of the kit standard. a dilution series is performed comparing the spiked versus the unspiked sample. Generally, samples with expected recovery and linearity between 80-120% are considered acceptable. This method can be used to validate any sample type that has not been evaluated by Boster Bio. for a more detailed spike and recovery protocol, please contact technical support.
Note: acceptable ranges should be determined individually by each laboratory. Additionally, technical support can help determine if a buffer component is not compatible with a given ELISA kit. please check the Citations tab on the product webpage for peer-reviewed papers utilizing a wide range of sample types. We also have an innovator's reward program where if the user validates our ELISA kits in applications or samples previously not validated by Boster Bio or other users, and share such information with us by submit a review, we will reward the user's efforts with a free antibody or ELISA kit from our catalog. Biocompare.com will also give $20 Amazon giftcard as an additional reward, if the review is submitted there as well.

Question
Q: What is the optimal O.D. value for HSP27 ELISA kit? I performed your HSP27 ELISA on serum samples. For my positive control, I received an O.D. value of 0.826, while my negative control received a value of 0.136. I obtained both of these controls from the ELISA kit, where your kit's typical data shows O.D. values much higher than my positive control and your background is lower. My samples O.D. values are around 0.225 and the highest is only 0.357. is it safe to say these samples contain HSP27 even though the O.D. values are not very high?
L. Surve
Verified customer
Asked: 2019-03-06
Answer
A: The absolute O.D. values may change according to incubation time. The more you incubate the higher the O.D. values are going to be. an important assessment should be is whether your sample O.D. values are statistically significantly higher than your blank values. in the above example, you could extend your development time in the substrate incubation step to obtain higher O.D. values, as long as your negative controls' O.D. values are not increasing faster in relation to your positive controls. typically, a sample with O.D. value 2 standard deviations higher than your negative controls can be considered positive. We calculate the sensitivity of this ELISA kit by changeing cutoff O.D. value, calculated as the average of 20 negative controls plus 2 standard deviations of the 20 negative controls, into a concentration. in other words, when we claim this HSP27 ELISA kit to have sensitivity of 5pg/ml, that means the minimum amount of HSP27 that can be declared/interpreted as positive by the above standard is 5pg/ml.

Question
Q: which procedure should I follow in order to thaw whole blood sample for HSP27 ELISA after freezing?
K. Hall
Verified customer
Asked: 2019-01-05
Answer
A: we do not recommend freezing and thaw whole blood. erythrocytes are fragile and, if frozen and thawed, will undergo hemolysis rendering the samples useless. To keep your blood samples to test HSP27 for a later time, you should let the blood clot in glass tubes and collect the serum to freeze for later use.

Question
Q: if the enzyme conjugated HSP27 antibodies are mixed with the substrate, will that convert the substrate into the enzymatic reaction product? Or the enzyme function is only activated when the antibody is attached with the HSP27 antigen?
Verified Customer
Verified customer
Asked: 2017-07-19
Answer
A: The enzyme is always active. Avoid contaminating the substrate with enzyme prior to the incubation otherwise it compromises the assay with false positive signal.
