Background of CTSL

Cathepsin L is an important lysosomal endopeptidase enzyme which is involved in the initiation of protein degradation. It also shows the most potent collagenolytic and elastinolytic activity in vitro of any of the cathepsins. The gene is mapped to 9q21-q22. It is a member of the Peptidase C1 family, which play an important role in diverse processes including normal lysosome mediated protein turnover, antigen and proprotein processing, and apoptosis. Cathepsin L has been reported in many organisms including fish, birds and mammals.

Intra Assay Consistency & Inter Assay Consistency

We measured random samples of Human Cathepsin L 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.

7 Customer Q&As for Human Cathepsin L ELISA Kit PicoKine®

Question

Q: how many samples can be assayed in a Picokine® ELISA Kit?

Verified Customer

Verified customer

Asked: 2020-07-16

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 vary slightly by kit so please refer to each datasheet for details.

Question

Q: how are cell lysates prepared for use in Picokine® ELISA kits?

V. Mitchell

Verified customer

Asked: 2019-12-06

Answer

A: for those Picokine® ELISAs where cell or tissue lysate is a validated sample type, sample preparation instructions for lysate can be found in the product insert. Components in lysate and lysis buffer can have an affect on immunoreactivity, so if lysate is not a validated sample type, care must be taken in sample preparation and validation.

Question

Q: if the enzyme conjugated Cathepsin L antibodies are mixed with the substrate, will that change the substrate into the enzymatic reaction product? Or the enzyme function is only activated when the antibody is attached with the Cathepsin L antigen?

Verified Customer

Verified customer

Asked: 2019-09-04

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: how to thaw whole blood sample for Cathepsin L ELISA after freezing?

Z. Tiwari

Verified customer

Asked: 2019-03-30

Answer

A: do not freeze 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 Cathepsin L for a later time, you should let the blood clot in glass tubes and separate the serum to freeze for later analysis.

Question

Q: Are Boster Bio recombinant proteins and antibodies sterile?

Verified Customer

Verified customer

Asked: 2018-11-30

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.
