Background of Haptoglobin
Haptoglobin (HP), is a protein that in humans is encoded by the HP gene. Haptoglobin, a plasma glycoprotein that binds free hemoglobin, has a tetrameric structure of 2 alpha and 2 beta polypeptides that are covalently associated by disulfide bonds. Haptoglobin is homologous to serine proteases of the chymotrypsinogen family. In the chimpanzee, there are 3 genes in the haptoglobin family (haptoglobin, HP; haptoglobin-related, HPR; and haptoglobin-primate, HPP), whereas only 2 genes exist in humans (HP and HPR). There are similarities between the primary structures of the alpha chain and of light chains of gamma globulins. The alpha haptoglobin locus is on the long arm of chromosome 16, where its exact cytogenetic location is 16q22.2. A major function of haptoglobin is to bind hemoglobin (Hb) to form a stable Hp-Hb complex and thereby prevent Hb-induced oxidative tissue damage. Haptoglobin is an unusual secretory protein in that it is proteolytically processed in the endoplasmic reticulum and not in the Golgi. The human haptoglobin HP*2 allele contains a 1.7-kb intragenic duplication that arose after a unique nonhomologous recombination between the prototype HP*1 alleles.

Intra Assay Consistency & Inter Assay Consistency
We measured random samples of Human Haptoglobin 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: can you recommend the dilution ratio of serum samples for detection of Haptoglobin in Human serum? I am trying to measure a few analytes and it requires 100ul of diluted samples for each well. We have limited sample volumes so we like to dilute as much as possible.
W. Puri
Verified customer
Asked: 2019-12-29
Answer
A: having little idea about the physiological or pathological context of your samples we cannot recommend a dilution ratio without performing a pilot test with your samples. Here is how you can perform a pilot study on your own: perform a serial dilution of your samples on the Haptoglobin ELISA kit to make sure you have a linear ascending curve followed by a plateau, which signifies the samples saturating the detection limit of the kit. Then you can pick the dilution ratios from samples in the linear part of the curve as your experimental dilution ratio.
If you are interested in using our ELISA service, you can also send us your sample and we will take care of everything for you. You can check our service details here: bosterbio.com/services/assay-services/ELISA-testing-service
Since you mentioned you have limited samples, our cost effective multiplex ELISA service would fit perfectly for your needs, where we can generate dozens of data points using as little as 25ul sample volume. Information on this service is also in the above link.

Question
Q: how can I thaw whole blood sample for Haptoglobin ELISA after freezing?
Verified Customer
Verified customer
Asked: 2019-12-06
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 Haptoglobin for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.

Question
Q: can you tell me how to prepare cell lysates prepared for use in Picokine® ELISA kits?
W. Thompson
Verified customer
Asked: 2019-07-28
Answer
A: for those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate are present in the product insert. Components in lysate and lysis buffer can impact immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Answered: 2019-07-28
Question
Q: if the enzyme conjugated Haptoglobin 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 Haptoglobin antigen?
Verified Customer
Verified customer
Asked: 2018-10-25
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.

Question
Q: Can Haptoglobin ELISA Kits be used with tissue homogenates (or other non-validated sample types)?
Verified Customer
Verified customer
Asked: 2017-05-15
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 a must. 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 assessd 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: how many samples can be assayed in a Picokine® ELISA Kit?
E. Kaur
Verified customer
Asked: 2015-03-27
Answer
A: The Picokine® ELISA Kits will generally run a 7-point standard curve, non-specific binding wells, and 39 samples in duplicate. this may depends upon the kit used so please refer to each datasheet for details.
